Follow each turn at your own pace.
Move 1 of 18: R'
Correct the 4x4 reduced-edge permutation parity that cannot occur on a legal 3x3.
W belongs to the Edge Swap group in PLL Parity.
Match the parity configuration
W 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' U R' U' R' U' R' U R U Rw2 U2 Rw2 R2 Uw2 Rw2 R2 Uw2
The opening is R' U R'; the final segment is Rw2 R2 Uw2. This version contains 18 face, wide, or slice turns and no whole-puzzle rotations.
