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.

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 ?
