of configurations, 19 958 400, is sufficiently small to allow a computer search for optimal solutions. The table below summarises the result of such a search, stating the number p of positions that require n moves to solve the six-colour Dino Cube (p2 for either solution, p1 for one specific solution): This table shows that the God's Number of the six-colour Dino Cube is 10 (when solving into either solution) or 11 (when solving into one specific solution). Variations Several shape modifications of the Dino Cube exist. These include the aforementioned BrainTwist, in the shape of a tetrahedron that can flip inside out, the Platypus, whose shape is also based on a tetrahedron, the Redi Cube, a cubic version with shallower cuts, and the Rainbow Cube, in the shape of a cuboctahedron. The latter three puzzles, unlike the Dino Cube, also have their "core" pieces visible. See also Skewb BrainTwist Pyraminx Duo Pocket Cube Skewb Diamond References Mechanical puzzle cubes
