How to dismantle a Rubik's Revenge.
The Rubik's Revenge (also known as the 4x4x4 cube, and normally referred to as the 4x4x4 or 4x4) is a twistable puzzle in the shape of a cube that is cut three times along each of three axes. The two main speedcubing brands are the Shengshou and the Dayan and MF8 cubes. These are some of the original brands for this puzzle, all of which were popular for speedcubing; but have been trumped by the new brands like Rubik's, patented by Peter Sebesteny in 1983, the East Sheen, patented by Chen Sen Li in 1999, and the Mefferts, which is a copy of the old Rubik's mechanism.
The Rubik's brand puzzle has no fixed centers, but a total of 24 center pieces, a total of 24 edge pieces, and 8 corners. It has 7.4 x 10^45 positions.
