Small ditetrahedronary prismatohexacosidishecatonicosachoron

The small ditetrahedronary prismatohexacosidishecatonicosachoron, or sadtapaxady, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra, 600 tetrahedra, 720 pentagonal prisms, and 120 small rhombidodecahedra. Four great ditrigonary icosidodecahedra, four tetrahedra, twelve pentagonal prisms, and twelve small rhombidodecahedra join at each vertex.
