The Group D3 |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Up to M-symmetry there are 208 cubes which exactly have the symmetries of this subgroup. All cubes but 4 up to M-symmetry are generated in 19 moves or less. 4 cubes needs 20 moves, they also have antisymmetry. They are depicted below, together with a few nicer examples of this class. The table gives the number of cubes up to M-symmetry which exactly have D3-symmetry, the average maneuver length is 17.81:
