4x4 Parity 【AUTHENTIC】
If you use the (the standard method for speedcubers), you solve your cross edges before finishing the remaining edge pairing.
A 4x4 cube does not have "center" pieces or true "edge" pieces; it has loose components that you group together. 4x4 parity
Most cubers fear the long OLL parity algorithm. However, its most useful feature is its symmetry. It relies almost entirely on slicing through the middle of the cube. If you use the (the standard method for
On a 4x4, you encounter the (one edge flipped) and PLL Parity (two edges swapped). 4x4 parity
