The Authors of the rubik Package
Prof. W.D. Joyner
of the United States Naval Academy wrote the routines to simulate the movements
of the Jewell, the Masterball, the Megaminx, the Rubik's 3x3 Cube, the
Rubik's 4x4 Cube and the Skewb for Maple 5. You can find the original functions
on the Homepage of Prof. W.D. Joyner. W.
Knoben of the RWTH Aachen updated these functions for Maple 6 and wrote
in addition the routines to simulate the movements of the pyraminx, the
Rubik's 2x2 Cube and the Rubik's 5x5 Cube. The functions to manipulate
movements are likewise written by W. Knoben.
