ABSTRACT:
A geometric device or puzzle in the form of a great dodecahedron is provided having a plurality of surface elements movable, without disassembly, about the surface of the puzzle. The puzzle can be visualized as being made up of twelve regular pentagons each with a five-pointed star pyramid centered thereon, with each of the five arms of the star pyramids being independently mounted and belonging to yet another star pyramid. The entire surface of the puzzle is made up of these independently mounted star arms. The arms are mounted on the body to permit rotation about the center axis of symmetry of each pentagon so that rotation of the star pyramids about their respective axes of symmetry causes permutations of the star arms. By suitable rotation of the various star pyramids, many permutations of the star arm elements over the entire surfaces of the puzzle may be effected and the individual star arms can be moved about the entire surface of the puzzle without disassembly.
