Move 1 of 17: R'
Correct the 4x4 reduced-edge permutation parity that cannot occur on a legal 3x3.
Adj Parity belongs to the Edge Swap group in PLL Parity.
Identify the parity case
The adjacent-edge parity case uses an outer-face adjustment around the inner-slice parity core to handle adjacent reduced edges.
Execute the algorithm
R' U R U' Rw2 R2 U2 Rw2 R2 Uw2 Rw2 R2 Uw2 U' R' U' R
The opening is R' U R; the final segment is R' U' R. This version contains 17 face, wide, or slice turns and no whole-puzzle rotations.
