Old Pochmann can be a problem with big cubes because Y-perm rotates the U-centers ccw 90 degrees. So if you're executing corners before the centers, you have to keep track of how many Y-perms you do.For 4x4 BLD corners I use Old POchmann so what's the parity fix for that?
Say we have the cycle (bUL->dFL->fUR)
bUL is the piece on the b slice (inner back slice), as well as the U slice (upper outer), and L slice (left outer). Locate each of those slices and you will find where they all meet. That is the bUL location.Which piece is bUL? I tried to figure this out with context clues from the full post, but I'm baffled. Is it the upper left edge on the back face? Is it the back edge of the edge pair on the upper location of the left face?
