Move 1 of 27: F
Correct the 4x4 reduced-edge permutation parity that cannot occur on a legal 3x3.
Sa belongs to the Diag Corner Swap group in PLL Parity.
Match the parity configuration
Sa 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.

The opening is F R U'; the final segment is Rw2 R2 Uw2. This version contains 27 face, wide, or slice turns and no whole-puzzle rotations.
