The orientation of your last layer edges has three possible cases: F R U R' U' F' F U R U' R' F' Do both of the above algorithms

1. 2. An ' apostrophe means you have to rotate a face counterclockwise 90 degrees. The 2 superscript means you have to rotate the face twice (180 degrees). No apostrophe or superscript means you have to rotate a face clockwise 90 degrees. 3. 4. • 2F ' = rotate 2 front face layers counterclockwise. • 3L 2 = rotate the 3rd left face 180 degrees.4x4 - Solving the last two centers.

OLL Parity Algorithm 1: This algorithm is the easiest to execute. It flips the two edge pieces as well as the corners. It also moves other edge pieces in the top layer. If your focus is speedsolving the 4x4 then this is the recommended algorithm. This should be done before you permutate the corners and edges of the last layer.Some useful algorithms/approaches for solving all PLL + Parity cases on even-layered cubes.
