Follow each turn at your own pace.
Move 1 of 19: y2
Correct the 4x4 reduced-edge permutation parity that cannot occur on a legal 3x3.
M belongs to the Adj Corner Swap group in PLL Parity.
Match the parity configuration
M 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.
