4x4 PLL Parity Algorithms

4x4 parity occurs on the last layer of a 4x4, where you get a case that is impossible to get on a 3x3 so you need a specific algorithm to solve it.  PLL parity specifically occurs because two adjacent edge pieces are swapped diagonally with 2 other adjacent edge pieces.  Generally you can't recognize it until you are at the PLL stage of solving.

PLL Parity case 1:

This swaps the 2 edges opposite each other. 

Perform the algorithm with Yellow on top.

PLL Parity case 2:

This swaps the 2 edges adjacent each other. Perform the algorithm with Yellow on top.

The diagrams are a bit misleading/confusing since the color illustrations that show the parity condition are top views but the illustrations of movements in the algorithm are front views. Nothing explicitly tells you the view angle was changed in the diagrams. This is good enough for those who understand the letters, but I figured the point of the movement diagrams was to make the algorithms more accessible to people who don’t.

Very impressive and happy to cheat on a 4×4

I already know how to solve parity but this alg is much easier .

Wdym? Algorithm 2 works perfectly fine

I dont really understand what to do in some cases. Like on case 2 of PLL parity i got confused. My point is, could u make it more clear please?

Really cool algorythms. Now i know how to solve parity without a resolve :)

which way should the cube face for this ?
