Move 1 of 28: R2
Setup: Uw2 R2 Rw2 Uw2 R2 Rw2 U2 R2 Rw2 x' L' R U2 x2 L2 R2 U2 x' L' R U x2 L2 R2 U x2 L2 R2
Correct the 4x4 reduced-edge permutation parity that cannot occur on a legal 3x3.
CwO belongs to the Edge Swap group in PLL Parity.
Match the parity configuration
CwO 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
R2 L2 x2 U' R2 L2 x2 U' R' L x U2 R2 L2 x2 U2 R' L x Rw2 R2 U2 Rw2 R2 Uw2 Rw2 R2 Uw2
The opening is R2 L2 x2; the final segment is Rw2 R2 Uw2. This notation uses 23 face or wide turns and 5 whole-puzzle rotations. Apply the setup to a solved cube before playing the algorithm.
