We never learn how, say, our smartphone works, we just forget that we don't understand it.
man it makes me happy to see ppl like him do things to entertain without boring us tf out in the process .... the quality is so good his vids got me into cubing
When I first started speedcubing wayy back on 2009, I tried to 'understand' the algorithm instead of simply 'memorizing' them, just like what you said in this video. Funny enough my first intuition for understanding the OLL & PLL algorithm was 'Destroy & Repair' instead of Commutator or Conjugate, and I've been training my cubing solely based on destroy & repair for about a year. At the peak of my skill, I could impress most of my peers using unconventional algorithm and 'shortcuts'. (In other words, just showing off) Sadly, I have stopped cubing for a very long time because I have lost my initial motivation of doing speedcubing, which was to 'Impress other people'. If there is anything you can take from my experience... When you learn something new, don't do it just to 'impress other people'.
“And a more appropriate word would be something like “sequence”, but in cubing we like to use big words to impress people because for some reason solving a cube is not impressive enough.” -A wise old man named Jay Permutation, 2021 *The truth hurts.*
Whenever I try teaching people to solve the cube I intentionally avoid the word "algorithm", opting instead for "sequence". It sounds less intimidating for people and so I find people are more willing to learn if you start by calling algs sequences instead.
hi dylan, i think i know why the 2 oll cases add up to a y perm. i imagine some years ago, when oll algs were being invented (with break and repair), someone noticed that if you do the first oll on a solved cube, you get the second oll. and once they solved the second oll, they noticed they had a different permutation of top layer pieces. with a bit more experimenting, they learnt to use these 2 olls together to make one pll. i havent confirmed this anywhere but this history of y perm makes the most sense to me.
actually tperm is like like that too, and I discovered an alg for Raperm this way: OLL 35, and OLL 37 in that order you can mess around with olls and discover plls
I have analysed exactly what the U perm does because of how often I use it, and it is really impressive to see how intelligently the algorithm is made to swap 3 edges and nothing else.
I've thought about this subject for a long time, and here is how think the history of cfop algorithms progressed: cross (intuitive) f2l (intuitive) on a solved cube, break one or more f2l pairs and repair them. see how this affects the top layer pieces. record down the algorithm and what it does. this gives you a lot of oll cases to play with. next, someone noticed that oll 37 + oll 33 on a solved cube leads to what we now know as y perm. im gonna guess this is the first pll discovered that involves both edge and corner pieces (because all edge only or corner only algs can be solved with somewhat intuitive commutators). from y perm, you can set up a bunch of other plls to it. some examples are j perm and t perm. with this new setup to _perm trick, you can explore many setups and get plls such as f perm and both n perms. i think once these 'basic' plls (edge only perms, corner only perms, y j t f n perms) have been discovered, people have already started using computers to solve any of the olls and plls that have not had their algs discovered yet. this irons out all leftover oll and pll cases, and today we have access to multiple algs of the same cases
this was such a great video! I have been cubing over a year and i have always watched many cubing related videos. This is one of my favourites!! Thanks Jperm!
Awesome videos, I’m a complete beginner and I’d love to see a tutorial of how to take apart the bigger cubes and also the minx’s too. I’ve found some other ones online but they’re not very good
@@kenp.7304 Actually, the most any loop on a cube can cycle is only about 1000 times. Meaning that if you just repeated some sequence of moves it would need to be a VERY long cycle, otherwise you just will never get there.
I never learned how it worked but I'm proud that I was able to figure out on my own that my 2-look alg was a Y-perm and then managed to figure out how to use it for 1-Look PLL.
Interesting that I intuitively used break and repair + trial and error on both the Miniminx and the 4x4 before learning the actual algs. Unefficient, but very satisfying.
It’s 12:14 in my country and it’s my birthday today and you made me even happy by uploading on my bday also I am supposed to sleep now but I am watching your vid
I think it’s funny that you display the break and repair algorithms as Alg1 + alg2 = alg3. Because you are soooooo close to the mathematical theory behind the rubicks cube. The cube is a type of Group. Groups are the mathematical objects used to study symmetry, and believe it or not, numbers are a group. So the reason why doing two algorithm one after the other yields the end state of a different algorithm is a result of the symmetrical structure of the rubik’s cube group. Worth researching a little bit. There is one method of solving the rubicks cube, where you can “intuitively” set the rubicks cube into a specific, but simple pattern, and afterwards you can use symmetry and group theory to quickly solve the cube. Great video! Time to play around with commutators.
Yes, "break and repair" method is easy to understand the concept but hard to understand each move. I classify it inside the method "shuffle", which is more general. My OLL method is created by that "shuffle" method.
The thing with break and repair is that different algorithms effect the parts you normally dont care about in different ways and this is even the case when using an alg, and then the mirrored inverse of itself, so while its more or less impossible to predict what is going to happen, you will definitely change something without destroying what you archived yet and that is always a good thing. For me break and repair is the most intuitive of the shown methods even if commutators are more powerful.
Speaking about algorithms, I found an R, U, D T-perm while messing around that felt really satisfying to do. It goes R2 U R2 U' R2 U' D R2 U' R2 U R2 D'. It has most likely been found before and might have even already been suggested. I know it isn't faster than the standard algorithm but it was fun to mess around with.
The Y Perm is not actually that difficult to understand. Like you said, it's 2 OLLs. The first (OLL) part, F R U' R' U' R U R' F' is basically a conjugate. After the first four moves (F R U' R') the top layer still has the same pieces on the layer, so if you were to change something only on that layer (like doing a U'), then reverse those first 4 moves, you wont have affected the bottom two layers, only the top layer. The second (OLL) part, R U R' U' R' F R F' is actually a commutator... not a corner commutator, but a block commutator, as in it cycles not just a corner or an edge, but a pair of them. If we rewrite the algorithm a bit, then it might be a bit easier to understand: (R U R' U') l' (U R U' R') l. The last two moves cancel out, but it's actually a commutator: A B A' B'. It's a 3 cycle of blocks, instead of corners or edges. And it just so happens that putting those together produces a diagonal corner swap, in this case a Y Perm. And you can actually change the algorithm so it doesn't move any corners, simply changing the second U' in the algorithm to a U. This doesn't really accomplish anything useful, but if you look, you can see that no corners have changed position and have just changed rotation (even after doing a 3 cycle, which doesn't preserve corner position) Hope this isn't too confusing haha :)
i didnt get how you can rewrite R U R’ U’ R’ F R F’ (the second OLL) in the other alg that you wrote.. can you explain it again? edit: now i got it.. oh boy thats brilliant
@@Humulator well first of all lets be sure that you didnt fall in the same stupid mistake that i did.. l’ = small L’ = Lw’ i didnt realize it immediately.. the first 4 moves are the same (R U R’ U’) than l’ means that your are turning the L slice and the M slice up that in the end is the same of doing R’ (that is the next move in the original alg) and a X move (so the center pf the cube in front of you goes in the top face).. at this point the next moves are F R F’.. but since we did a X move all the F moves becomes U moves and F’ becomes U’ while the R remains R. at this point the sequence is done but to complete the commutator we need to undo the l’ move with a l move. The clever idea is that we also add a R move and you should realize that l’ + R is not changing anything in the cube ;)
I was wait for this since 3 days but i was waiting for q and a but ok i was checking community page to see that q and a time question down your commets and right now i am in india 12 : 18 am mid night
A Y perm is actually possible to construct intuitively, funnily enough. It's just a conjugated cyclic shifted J perm, and J perm is a block comm with an extra move to make it a 2e2c. There are definitely some completely unintuitive algs, but y perm isn't exactly one of them
Sorry I know this is an old comment, but would you mind explaining a bit more? What's does 'conjugated cyclic J perm mean? What's a block comm? 2e2c means 2 edges 2 corners? I would love to know what you mean
@@beanzthumbz So a commutator (like J perm shows in the video) normally affects 3 pieces. However, you can affect more pieces if you use wide moves. For example, the commutator F' l F R' F' l' F R (written as [F' l F, R'] in comm notation, if you're familiar with that) cycles round 3 blocks of pieces. This is called a block comm. Doing R U' R' after that block comm will place all 3 blocks that were affected onto the U layer. That means that we can do R U R' [the block comm] R U' R' to turn it into a last layer algorithm, which is a conjugate, as J perm describes in the video. Writing that alg out in full gives R U R' F' l F R' F' l' F R2 U' R', which is just another way of writing the standard J perm. So the standard J perm is a conjugated block comm. Writing it that way means it's a 3E3C alg (3edges 3 corners), because those are the affected pieces. If we add a U' at the end however, it becomes a 2E2C alg, because 2 of the blocks we cycled get returned to their original places, and one block that wasn't affected now is. So the 2E2C version of J perm (that we'll use going forward) is R U R' F' R U R' U' R' F R2 U' R' U' (the last move is important here). Now, this affects 2 edges and 2 corners, and we can manipulate it to affect other combinations of 2 edges and 2 corners. For example, if we do R' U' [J perm] U R, we get a ZBLL (a lot of people use this as a COLL alg too). This was a way of conjugating the J perm, but if you write it out fully it looks like: R' U' R U R' F' R U R' U' R' F R2 U' R' U' U R. You might notice that the last 4 moves cancel themselves out, so in reality the full alg is R' U' R U R' F' R U R' U' R' F R2 U'. This is a conjugate of J perm, but because the setup we did cancelled fully with the end of the alg, it's the same length as the original alg. Essentially what we've done is just taken the last 2 moves from the end of the alg and shifted them to the start. This is a technique known as cyclic shifting. If we take J perm and instead shift 4 moves from the start to the end (the R U R' F') then we actually end up with T perm. It's just a cyclic shifted J perm, so it too can be seen as a setup into a block comm. Going a bit further with this, if we take T perm (R U R' U' R' F R2 U' R' U' R U R' F') and shift another 4 moves from the start (the R U R' U') then the alg we end up with is actually the swapping alg we use in old pochmann corners (this is for blindfolded solving, so don't worry about it if you don't know blind. The important thing is it's an alg that swaps UB with UL, and UBL with RDF). Now, we can keep cyclic shifting this alg but eventually we'll just end up back at J perm (hence the "cyclic" bit of "cyclic shift"). So we're going to stop here, with the alg R' F R2 U' R' U' R U R' F' R U R' U'. However, since 3/4 of the pieces affected by this alg are in the U layer, and the third is in RDF (which is easy to set up to the U layer) we can conjugate THIS alg, and get another LL algorithm. Doing F [this alg] F' means it's going to swap UBL with UFR instead (and still swap UB with UL), which means we've just created Y perm.
@@cookierobber thanks for taking the time to write this! Unfortunately I’m kind of stuck at the start. I recognise that alg, you can use it in F2L to inset an oriented edge in the top layer into its slot. And I can see that it cycles 3 2x1 blocks, so calling it a block comm makes sense. But how is this even a comm at all? Maybe I just don’t understand commutators deeply yet, because I can’t wrap my head around how this works since all the blocks aren’t in the same layer. The idea of block comms is cool though, I just invented this shitty Nb perm with it: [RFR’URF’R’U’RFR’, U2]
@@beanzthumbz Well, a commutator doesn't require all the pieces to be in the same layer, just 2 of them. Here 2 of the blocks are in the R layer, so it's fine. But anyway, a normal commutator has a 3 move insertion and a 1 move interchange. The insertion needs to affect only 1 piece on the interchange layer. So F' L F R' F' L' F R would be an example of a commutator that cycles 3 corners. F' L F is the insertion, moving BUL into RUF, and R' is the interchange, moving RUB into RUF. So the commutator as a whole cycles BUL>RUF>RUB. Now, the block commutator I gave is a modified version of this. Instead of F' L F, the insertion is F' l F. This still moves BUL into RUF, but it also moves BU into RF. Normally an insertion needs to affect just one piece on the interchange layer (the R layer in this case). Here it affects 2 adjacent pieces (RUF and RF), but we can kind of think of them as one piece, since they don't get broken up at any point in the alg. So rather than cycling 3 individual pieces, the block comm cycles 3 corner-edge blocks (BU/BUL>RF/RUF>RU/RUB). If you imagine a cube where these blocks are attached together and actually *are* 1 piece it might make it easier to understand - on such a cube, the block comm would just be cycling 3 pieces, like the normal comm I showed above.
@@cookierobber Ok yeah this makes sense now cheers. I was getting confused cause I'm not used to seeing the interchange layer as R, and wide moves muck up my visualisation.
Lmao the only reason I learnt how to solve it was to impress people now I've fallen into the rabbit hole of speed cubing now lol

I've thought about this subject for a long time, and here is how think the history of cfop algorithms progressed:
cross (intuitive)
f2l (intuitive)
on a solved cube, break one or more f2l pairs and repair them. see how this affects the top layer pieces. record down the algorithm and what it does. this gives you a lot of oll cases to play with.
next, someone noticed that oll 37 + oll 33 on a solved cube leads to what we now know as y perm. im gonna guess this is the first pll discovered that involves both edge and corner pieces (because all edge only or corner only algs can be solved with somewhat intuitive commutators).
from y perm, you can set up a bunch of other plls to it. some examples are j perm and t perm. with this new setup to _perm trick, you can explore many setups and get plls such as f perm and both n perms.
i think once these 'basic' plls (edge only perms, corner only perms, y j t f n perms) have been discovered, people have already started using computers to solve any of the olls and plls that have not had their algs discovered yet. this irons out all leftover oll and pll cases, and today we have access to multiple algs of the same cases

the first 4 moves are the same (R U R’ U’) than l’ means that your are turning the L slice and the M slice up that in the end is the same of doing R’ (that is the next move in the original alg) and a X move (so the center pf the cube in front of you goes in the top face).. at this point the next moves are F R F’.. but since we did a X move all the F moves becomes U moves and F’ becomes U’ while the R remains R. at this point the sequence is done but to complete the commutator we need to undo the l’ move with a l move. The clever idea is that we also add a R move and you should realize that l’ + R is not changing anything in the cube ;)
These videos help us alot , on the technical side too , keep it up bro
Great video as always. Also.....damn you're approaching 1 mil subs :O....congrats!
Wait how is there 462 views when the video cameout 2 minutes ago and its 8:26 minutes long???????
I was wait for this since 3 days but i was waiting for q and a but ok i was checking community page to see that q and a time question down your commets and right now i am in india 12 : 18 am mid night
I hope your doing well with all that's happening India due to Covid
Thanks for your commet and yaa everthing is going well because vaccination started and were u live how's covid there
Because because of lockdown i am 24 hour online right time is 01 : 01 am
@@pushpaghoge5798 I live in Canada Covid isn't bad here still closed down in Ontario but we're pretty chill
Ok bye let me sleep for an hour i will met u after my sleep is over just a hour sleeep a day
Execellent explanation! Thanks.
Congrats for reaching the 600k!!🥳
A Y perm is actually possible to construct intuitively, funnily enough. It's just a conjugated cyclic shifted J perm, and J perm is a block comm with an extra move to make it a 2e2c. There are definitely some completely unintuitive algs, but y perm isn't exactly one of them
Sorry I know this is an old comment, but would you mind explaining a bit more? What's does 'conjugated cyclic J perm mean? What's a block comm? 2e2c means 2 edges 2 corners? I would love to know what you mean
@@beanzthumbz So a commutator (like J perm shows in the video) normally affects 3 pieces. However, you can affect more pieces if you use wide moves. For example, the commutator F' l F R' F' l' F R (written as [F' l F, R'] in comm notation, if you're familiar with that) cycles round 3 blocks of pieces. This is called a block comm. Doing R U' R' after that block comm will place all 3 blocks that were affected onto the U layer. That means that we can do R U R' [the block comm] R U' R' to turn it into a last layer algorithm, which is a conjugate, as J perm describes in the video. Writing that alg out in full gives R U R' F' l F R' F' l' F R2 U' R', which is just another way of writing the standard J perm. So the standard J perm is a conjugated block comm. Writing it that way means it's a 3E3C alg (3edges 3 corners), because those are the affected pieces. If we add a U' at the end however, it becomes a 2E2C alg, because 2 of the blocks we cycled get returned to their original places, and one block that wasn't affected now is. So the 2E2C version of J perm (that we'll use going forward) is R U R' F' R U R' U' R' F R2 U' R' U' (the last move is important here). Now, this affects 2 edges and 2 corners, and we can manipulate it to affect other combinations of 2 edges and 2 corners. For example, if we do R' U' [J perm] U R, we get a ZBLL (a lot of people use this as a COLL alg too). This was a way of conjugating the J perm, but if you write it out fully it looks like: R' U' R U R' F' R U R' U' R' F R2 U' R' U' U R. You might notice that the last 4 moves cancel themselves out, so in reality the full alg is R' U' R U R' F' R U R' U' R' F R2 U'. This is a conjugate of J perm, but because the setup we did cancelled fully with the end of the alg, it's the same length as the original alg. Essentially what we've done is just taken the last 2 moves from the end of the alg and shifted them to the start. This is a technique known as cyclic shifting. If we take J perm and instead shift 4 moves from the start to the end (the R U R' F') then we actually end up with T perm. It's just a cyclic shifted J perm, so it too can be seen as a setup into a block comm. Going a bit further with this, if we take T perm (R U R' U' R' F R2 U' R' U' R U R' F') and shift another 4 moves from the start (the R U R' U') then the alg we end up with is actually the swapping alg we use in old pochmann corners (this is for blindfolded solving, so don't worry about it if you don't know blind. The important thing is it's an alg that swaps UB with UL, and UBL with RDF). Now, we can keep cyclic shifting this alg but eventually we'll just end up back at J perm (hence the "cyclic" bit of "cyclic shift"). So we're going to stop here, with the alg R' F R2 U' R' U' R U R' F' R U R' U'. However, since 3/4 of the pieces affected by this alg are in the U layer, and the third is in RDF (which is easy to set up to the U layer) we can conjugate THIS alg, and get another LL algorithm. Doing F [this alg] F' means it's going to swap UBL with UFR instead (and still swap UB with UL), which means we've just created Y perm.
@@cookierobber thanks for taking the time to write this! Unfortunately I’m kind of stuck at the start. I recognise that alg, you can use it in F2L to inset an oriented edge in the top layer into its slot. And I can see that it cycles 3 2x1 blocks, so calling it a block comm makes sense. But how is this even a comm at all? Maybe I just don’t understand commutators deeply yet, because I can’t wrap my head around how this works since all the blocks aren’t in the same layer. The idea of block comms is cool though, I just invented this shitty Nb perm with it: [RFR’URF’R’U’RFR’, U2]
@@beanzthumbz Well, a commutator doesn't require all the pieces to be in the same layer, just 2 of them. Here 2 of the blocks are in the R layer, so it's fine. But anyway, a normal commutator has a 3 move insertion and a 1 move interchange. The insertion needs to affect only 1 piece on the interchange layer. So F' L F R' F' L' F R would be an example of a commutator that cycles 3 corners. F' L F is the insertion, moving BUL into RUF, and R' is the interchange, moving RUB into RUF. So the commutator as a whole cycles BUL>RUF>RUB. Now, the block commutator I gave is a modified version of this. Instead of F' L F, the insertion is F' l F. This still moves BUL into RUF, but it also moves BU into RF. Normally an insertion needs to affect just one piece on the interchange layer (the R layer in this case). Here it affects 2 adjacent pieces (RUF and RF), but we can kind of think of them as one piece, since they don't get broken up at any point in the alg. So rather than cycling 3 individual pieces, the block comm cycles 3 corner-edge blocks (BU/BUL>RF/RUF>RU/RUB). If you imagine a cube where these blocks are attached together and actually *are* 1 piece it might make it easier to understand - on such a cube, the block comm would just be cycling 3 pieces, like the normal comm I showed above.
@@cookierobber Ok yeah this makes sense now cheers. I was getting confused cause I'm not used to seeing the interchange layer as R, and wide moves muck up my visualisation.
