Move 1 of 24: R

Setup: x' L' R Rw U2 Rw U2 Rw' U2 Rw U2 Lw' U2 Rw U2 Rw' U2 Rw' x' U2 Rw' x L R'

Correct the 4x4 reduced-edge orientation parity before continuing with a 3x3-style finish.

Match the parity configuration

M combines its named edge configuration with the parity correction. Use the inverse of this exact sequence to establish its training position; a different parity entry can require a different piece arrangement.

Execute the algorithm

R L' x' Rw U2 x Rw U2 Rw U2 Rw' U2 Lw U2 Rw' U2 Rw U2 Rw' U2 Rw' R' L x

The opening is R L' x'; the final segment is R' L x. This notation uses 21 face or wide turns and 3 whole-puzzle rotations. Apply the setup to a solved cube before playing the algorithm.
