A perm not possible using 2 faces?

[Jake Gouldon]

I use R' F R' B2 R F' R' B2 R2

I use a wierdish fingertrick for the B2's though, and it's performed more like Lw' U R' D2 R U' R' D2 Lw R (not Lw2 or R2, then you don't get the U-face back on top for AUF)

I use the same alg as Jake with an intuitive x' between F and R' just because it feels right (I remember the alg as R' F R' B2 R F' R' B2 R2 but I actually do R' F x' R' U2 R B R' U2 R2)

Correct me if I'm wrong, but I'm fairly sure that 2-gen corner PLLs can't exist.

Correct. I really hated the A Perm but some of these algs are beasts.

R2 U2 R U2 R2 U2 R2 U2 R U2 R2 U2

R2 U2 R U2 R2 U2 R2 U2 R U2 R2 U2

Let me rephrase: No 2-gen alg can change the permutation of the U layer corners relative to each other and preserve the E and D layers. I think that works.

R2 U2 R U2 R2 U2 R2 U2 R U2 R2 U2

That doesn't count as a corner PLL since it is H permutation with a U2 at the end.

For the A permutation, I use x R' D R' U2 R D' R' U2 R2 (Headlights facing away from you).

I don't know. It did change the positions of all U layer corners, though so would U, U2, or U'.

I just use this one, I only look at 1 corner and i already know what algorithm and where it wants to go.

What A perm is this:

Thats the A(a) perm in which that corner wants to go to the upper left corner, the upper left corner goes to the upper right, and the upper right goes to the front right. Satisfied??

x (R’ U R’) D2 (R U’ R’) D2 R2

To clear things up- While keeping all edges and other corners in the same permutation, it is NOT possible to change the permutation of the LL corners with only 2-gen algorithms. There's a proof somewhere but I can't find it...

Do you know T perm? Do T perm, but change all R moves to double layer turns.

You have just blown my mind.

R U R' F' x L U R' U' L' U R2 x' U' R'

hopefully i typed that out right

Do you do it that way? I prefer this: R U R' F' r U R' U' r' F R2 U' R'

Can someone add these to the wiki? For some reason, my email confirmation allowing me to edit articles was never received.

Yes add them add them.

 

[JTW2007]

I'd add them, but I can't edit the wiki either.

x (R’ U R’) D2 (R U’ R’) D2 R2

Not at all. How do you know that the upper left corner doesn't go to the lower left?

Obviously its a triple A perm
