[30 F, 84 E, 56 V] This model is a replica of naturally occurring crystals in the isometric crystal system. It has tetrahedral symmetry. It is a combination of forms: Its thirty faces are each a portion of one of the six faces from the cube, twelve faces from the rhombic dodecahedron, or twelve faces from the triakis tetrahedron, of which this model is the intersection.
