4x4
Follow each turn at your own pace.
Move 1 of 18: Rw
Correct the 4x4 reduced-edge orientation parity before continuing with a 3x3-style finish.
Identify the parity case
Recognize one reduced edge with an orientation defect. This basic sequence can also change the last-layer permutation, so use it before the permutation stage.
Execute the algorithm
Rw U2 x Rw U2 Rw U2 Rw' U2 Lw U2 Rw' U2 Rw U2 Rw' U2 Rw'
The opening is Rw U2 x; the final segment is Rw' U2 Rw'. This version contains 17 face, wide, or slice turns and 1 whole-puzzle rotation.
