Double parity is when you get OLL and PLL parity. Lucasparity does not solve PLL parity; it's only an OLL parity alg. A double parity alg does something like:I have a question about 4x4. What is double parity? Are there different algs that solve both the parity cases at once? Is it all right if I use the Lucas Double Parity alg for OLL Parity? Will it affect PLL?
Rw2' F2 Rw U2 Rw U2' x U2 Rw U2' Rw' U2 Rw U2' Rw2' U2' x' [U2]
As far as I know, most people don't try to solve both parities in one step; they solve OLL parity, then if they get PLL parity the do that separately. It takes far too much time to recognise double parity. But some people use double parity algs for OLL parity just because they prefer that alg to the normal OLL parity alg.
