Follow each turn at your own pace.
Move 1 of 22: Rw'
Correct the 4x4 reduced-edge orientation parity before continuing with a 3x3-style finish.
Identify the parity case
The pure variant flips the target reduced edge while preserving the corners and the other reduced edges. It is useful when retaining their current permutation matters.
Execute the algorithm

The opening is Rw' R U2; the final segment is Rw2 R2 F2. This version contains 22 face, wide, or slice turns and no whole-puzzle rotations.
