Here are the steps for fixing the 4×4 Rubik’s cube parity:

Steps: R2, T2, R2, TH2, R2, TH2

Here are the abbreviations:

R: Right

T: Top

TH: Top Half (for 4×4 this is the top two layers)

Here are the steps to fix the parity when solving a 4×4 rubik’s cube:

Edge Parity: RD1, T2, LD1, F2, LU1, F2, RD2, T2, RU1, T2, RD1, T2, F2, R2, F2

The abbreviations are as follows:

RD – Right Down

LD – Left Down

RU – Right Up

RD – Right Down

T – Top

F – Front
