The Independence of OLL and PLL Parities
Why getting OLL parity on a 4×4 tells us nothing about PLL parity, explained through permutations and a couple of algorithms.
On a 4×4, if we have OLL parity, does that tell us anything about whether we’ll also get PLL parity? The usual answer is no. But why can one edge look flipped, or two edges look swapped, when neither is possible on a 3×3? Let’s look at what we’re actually permuting.
