4x4x4 Parity

[jackolanternsoup]

chris hardwick said on his page it's possible to avoid corner parity (PLL) with a little forethought so i'd like to know how....

And is there a faster algorithm to solve edge OLL parity?

You can solve OLL-Parity with 1 alg
You can solve PLL-Parity with 1 alg
You can solve OLL+PLL-Parity with 1 alg.

And how are we supposed to know if there is a faster algorithm if you don't post the one you use right now?

okay i use the

r2 B2 U2 l U2 r' U2 r U2 F2 r F2 l' B2 r2

okay i use the

r2 B2 U2 l U2 r' U2 r U2 F2 r F2 l' B2 r2

Double layer turns make the algorithm faster but you will have to recognize parity and execute the parity algorithm immediately after F3L

AUF to set up an easy OLL.

What' Auf? lol sorry I'm not very familiar with terms and stuff..

You can avoid the corner parity if after spotting that you have the PLL parity you choose to see the pseudo-case as a PLL alg that will still solve the corners. So fix the edges to the actual corner case in your mind, then at the end you only need to fix the edges PLL-parity case to solve the cube. That's what I meant on my site about avoiding the corner parity with some forethought.

AUF = Adjust U Face = turn the upper layer so that the already solved pieces comes in place.
