A center 4x4x4 is a cube that has been cut into smaller pieces. Each piece is then put back together in the same order as the original cube. The process of solving a center 4x4x4 can be divided into two parts: first, the centers must be solved; second, the edges must be solved.
The centers of a 4x4x4 are the six faces that are not on the edge of the cube. To solve the centers, each face must be turned so that all four colors match up. This can be done by using algorithms, or by inspection. Once all of the centers are solved, the edges can be solved.
The edges of a 4x4x4 are the twelve pieces that are on the edge of the cube. To solve the edges, each piece must be placed in its correct location and orientation. This can be done by using algorithms, or by inspection.
