That case shouldn’t be possible. My guess is some stickers may have gotten swapped

R U R’ U’ — setup
(Take r as a slice turn)
l’ U2 l U2 l U2 r’ U2 l U2 l’ U2 F2 l2 F2 r

U R U’ R’

Edit :If you don’t have wifi, how did you post this?

The exact case as in the picture is indeed impossible, but what's possible are cases like these:

For these, the solution is as 1001010101001 mentioned: do some setup moves to bring the two pieces you want to swap to the UFr and UBr positions, do that alg, then undo the setup moves.

And where did you find it?

4x4x4 parity algorithms on the wiki contain a huge collection of algorithms, including l’ U2 l U2 l U2 r’ U2 l U2 l’ U2 F2 l2 F2 r.

Technically the Alf that I posted is ‘true’ parity because it swaps two edges while PLL parity swaps four edges in a 2x2 cycle.

For pll has anyone compiled a list of algs for the remaining cases with parity?
Thanks in advance

If you mean for PLL parity, I put quite a few algorithms for most of the 22 PLL Parity cases at the beginning of the 4x4x4 parity algorithms Wiki page. I have included all (or at least most) of the original algorithms found for these cases back at the beginning of the century.

I am aware that there have been several videos of PLL parity tutorials featuring new (and possibly faster) algorithms for each of the cases, but I lost track of them. If someone does his or her research and figures out which algorithms for PLL parity cases which are already not in the Wiki and lists them here, I will add them to the Wiki.

Is there a nice way to solve this pll parity case?
Set Up: (V Perm) U2 R U R' U' (PLL Parity) U' R U' R'

Just do PLL parity + E perm.

Alternatively, Uw2 Rw2 U2 Rw2 R' D R' U' R (U2 D') R' D' R U2 R' (U' D) Rw2 Uw2, or one of the algs in the wiki page linked in the post directly above yours.

If I'm not wrong you can do a y perm and in the middle of the first oll (of the y perm) you can insert the pll parity.

That solves a different case.

Does anyone have any idea of what TPS is needed for sub 1?

A solve with Yau takes 120-160 moves, so you'd need roughly 2.4 tps to be sub-1.

i ever accidentally get this condition, i did oll algorithm but i realised this condition so i reversed oll algorithm before oll algorithm is done and i did oll parity 2 times

if you get this condition :

do oll parity algoritm 2 times with this algorithm

(Rr)2 B2 U2 (Ll) U2 (Rr)' U2 (Rr) U2 F2 (Rr) F2 (Ll)' B2 (Rr)2

and your 4x4 will be solved

 

[Brest]

do oll parity algoritm 2 times with this algorithm

(Rr)2 B2 U2 (Ll) U2 (Rr)' U2 (Rr) U2 F2 (Rr) F2 (Ll)' B2 (Rr)2

and your 4x4 will be solved

F U' R2 D R' U2 R D' R2 U F'

So, I’m not sure if this is the appropriate place to put this question, but the title of this thread is quite vague, so I’ll just throw the question. I’m having trouble with my AoSu GTS M. Nothing seems wrong with the mechanism. No pieces are broken and the centers are put in correctly. However, when I turn the inner layers, the centers will frequently misalign.
This is really troubling as I have tried disassembling the cube and reassembling the cube multiple times. I have also assured that the centers are put into the right spots and oriented correctly. Can anyone please find a solution? The cube used to be my main before this incident.

 

[Duncan Bannon]

Antoine Cantin has a video about Auso Gts m potential problem. I'd check it and see if that is it.

I’ll try it out. Thanks!

what would u do if u get diagonal corner swap ?
i can solve but i want to know what would u do

 

[xyzzy]

what would u do if u get diagonal corner swap ?

Y perm with inserted PLL parity.
