PLL's I can do now on my 4 X 4 without stopping in the middle of one and not knowing how to complete the damn thing

Yeah I have that problem too, and on 3x3 when a have an epic fail that's usually the reason - cube catches mid-PLL and I have no idea where I am or how to recover! Hello 50 second solve.

R U R' U' // sexy move
2R2 U2 2R2 u2 2R2 2U2 // permutation parity
U R U' R' // inverse sexy move

you can also use

R' U R U'
2R2 U2 2R2 u2 2R2 2U2
U R' U' R

This is a conjugate. The sexy move positions one of the unsolved edges so that it is opposite the other. Once this has been setup the standard permutation parity swaps them. Then you undo the setup to complete the conjugate.

Or you can just do permutation parity and a Uperm.

Thanks, I like that!

However, I found that your perm parity alg might be off, I did sexy -> r2 U2 r2 Uw2 r2 u2 > sexy'

And the single dedge flip:

r2 U2 r2 U2
r  U2 r  U2
r' U2 B2 U'
r' U  B2 U'
r  U'

I simplified that notation as this is much easier to remember, pattern wise

So when you do 4x4 do you solve it 'fully' and then do the parity algs? Your alg above is a big hard with all the inner r/r' moves (IMHO). I prefer to do orientation parity before OLL so that you can just use Rw/Rw'/Rw2 etc since the corners don't matter and I think it's easier. On the other hand, I kind of pick and choose to do the perm parity before or after PLL depending on the situation .

EDIT: Nevermind, the above alg flips 2 other edges (on the B face) if you do Rw moves.

I generally do the old school Rw2 B2 U2 Lw U2 Rw' U2 Rw U2 F2 Rw' F2 Lw' B2 Rw2 for flipping an edge and I've seen it done with all Rw and Lw replace with r and l and I don't think it's necessary if you do it before OLL but you alg doesn't work that way in these regards.

2R2 U2 2R2 u2 2R2 2U2 = r2 U2 r2 Uw2 r2 u2

The first alg is in SiGN notation, the other one is WCA

 

[littlewing1208]

2R2 U2 2R2 u2 2R2 2U2 = r2 U2 r2 Uw2 r2 u2

The first alg is in SiGN notation, the other one is WCA

Ahhh, I thought that (2R)2 was equivalent to Rw2 , thanks for the clarification.

OLL Parity:

PLL Parity:

r is the same as Rw2 R2

r2 U2 r2 Uw2 r2 U2 Uw2 (I think)

 

[littlewing1208]

OLL Parity:

Is this the alg from the video? Rw U2 x Rw U2 Rw U2 Rw' U2 Lw U2 Rw' U2 Rw U2 Rw' U2 Rw'

I just found that one on cubewhiz and I think I kind of like it better than the one in my post above (no B or F move ) despite the cube turn.

Yep. It's awesome

Marcel has a good example on video on how he does it. I did it differently but adopted his method now.

 

[MarcelP]

OLL Parity:



PLL Parity:

r is the same as Rw2 R2

r2 U2 r2 Uw2 r2 U2 Uw2 (I think)

Kunaal, you are a rock star you know? That looks so freaking awesome.. and you have that cube only for like a week. LOL

 

[Kattenvriendin]

I use this now (thank you Brest!):

Two adjacent dedges swap parity: (keep to swap on front and right)

R U R' U'
r2 U2 r2 Uw2 r2 u2
U R U' R'

That notation was easiest for me Just have to remember it now.. along with the different grips I learned from Marcel



"r is the same as Rw2 R2"

I do it slightly different, for r2 that is:

Hold R with right hand thumb on front, fingers on back.

Do R2', then slide fingers and thumb over to include the r layer and move it up doing Rw2



For a single r I do the same, just R', slide over and move up doing Rw.

If you have a good duble flick U2 you could try this OLL parity alg: Lw' U2 Lw' U2 Lw U2 Lw' U2 Rw U2 Lw' U2 Lw U2 x' Lw U2 Lw
Every 2nd move is a U2.

It was very easy for me to learn and it's quite fast too

 

[Kattenvriendin]

Nice single dedge flip

It'll flip the entire top front edge side (so not just the dedge but also the corners get flipped) and swap the left and right dedges? Is that correct?

 

[PianoCube]

That sounds about right. It also twists the U center a half round, but you'll probably not notice it.

 

[Lchu613]

Can someone help me out with notation on 4x4?
w turns are two layers at once, while little letters are the inner slice, right? Or wrong?


*Confused*

EDIT: Got it

 

[Kattenvriendin]

It's right.

Man I would love it if there would be an unread thingie in front of the topic if there were things unread in there. Must be the move.

 

[mark49152]

Yeah that's why they moved you. People were complaining that you "clutter" the unread posts list. Sad eh.

 

[littlewing1208]

I think she meant that now the thread is showing as completely unread due to the move as opposed to retaining the history of when she last checked. After checking it for the first time yesterday in OT, it now jumps to the first unread fine for me.

 

[Kattenvriendin]

Works fine now.. it showed as completely read. It's ok I check here often enough.


And yeah.. people are sometimes sad. "There is an X in the top right corner, click it", is what I think LOL


anyway.. my AO5 and AO12 got improved *grin*

 

[Lchu613]

Geez, I'm still something like 5 minutes

UPDATE: First timed solve, 2.51.37

I'm not sure, but I suspect I got lucky with the edge pairing

 

[Kattenvriendin]

That is a REALLY good time to start out with! Well done!


The v-4 is still my main, I really like it. It is breaking in so well that I have now inserted two washers per side in there, along with the already in there heaviest springs. Imagine that!



Oh to add.. I have had a finger cleft in my thumb now for 4 weeks.. is ouch, and won't go away so now I am having the thing wrapped up and all.

Cubing feels stupid with right thumb in bandages.
