A Zonohedron which is the Dual Polyhedron of the Icosidodecahedron. It is composed of 30 Rhombuses joined at 32 vertices. Ede (1958) enumerates 13 basic series of stellations of the rhombic triacontahedron, the total number of which is extremely large. Messer (1995) describes 226 stellations. The intersecting edges of the Dodecahedron-Icosahedron Compound form the diagonals of 30 Rhombuses which comprise the Triacontahedron. The Cube 5-Compound has the 30 facial planes of the rhombic triacontahedron (Ball and Coxeter 1987).
