Move 1 of 28: F
Correct the 4x4 reduced-edge permutation parity that cannot occur on a legal 3x3.
Diag C belongs to the Diag Corner Swap group in PLL Parity.
Match the parity configuration
Diag C 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 F R F'. This version contains 28 face, wide, or slice turns and no whole-puzzle rotations.
