4x4 - OLL Parity

All of these work with both wide (Rw or Lw) and inner turns (r/2R or l/2L). I recommend checking out what both does on the cube, as wide turns can effect pieces you might not want if you are executing these during the 3x3 phase. Thus I put both versions in my examples.

Pure

Basic

Comment If you use it on this case, it will end in a headlight OLL.

M into finished OLL

Algorithm (l r') Rw2 B2 U2 Lw U2 Rw' U2 Rw U2 F2 Rw F2 Lw' B2 Rw2 (l' r)
Comment (l r') is a wide M, (l' r) is a wide M', but those are not valid turns on even cubes.
