Follow each turn at your own pace.
Move 1 of 21: y2
Correct the 4x4 reduced-edge permutation parity that cannot occur on a legal 3x3.
Ca belongs to the Adj Corner Swap group in PLL Parity.
Match the parity configuration
Ca 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.
