The ultimate solution 4x4x6 cuboid the 4x4x6 cuboid is a cuboid which can be thought of as a 4x4x4 rubiks revenge with an extra layer on top and bottom. The centers you have formed on a 4x4 are equivalent to the single centers on a 3x3, and each pair of two 4x4 edge pieces is equivalent to a single edge on a 3x3 cube. I have taken care to choose algorithms that i think are easy to both memorise and perform, and i have arranged them in an order that i think facilitates learning.
Since all oll parity algorithms contain an odd number of inner slice quarter turns, one can technically fix any 4x4x4 wing edge odd parity case by executing a single slice quarter turn and then resolve the cube using an even number of inner slice quarter turns. Edge pairing does not affect the oll parity state because each pairing is just a set of two even inner slice moves.
