Move 1 of 26: Uw2
Setup: x2 L2 R2 U' x2 L2 R2 U' x' L' R U2 x2 L2 R2 U2 R Rw2 3Rw U2 L2 Lw2 Uw2 L2 Lw2 Uw2
Correct the 4x4 reduced-edge permutation parity that cannot occur on a legal 3x3.
CcwO belongs to the Edge Swap group in PLL Parity.
Match the parity configuration
CcwO 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
Uw2 Lw2 L2 Uw2 Lw2 L2 U2 3Rw' Rw2 R' U2 R2 L2 x2 U2 R' L x U R2 L2 x2 U R2 L2 x2
The opening is Uw2 Lw2 L2; the final segment is R2 L2 x2. This notation uses 22 face or wide turns and 4 whole-puzzle rotations. Apply the setup to a solved cube before playing the algorithm.
