Small dipentary disprismatohexacosidishecatonicosachoron

The small dipentary disprismatohexacosidishecatonicosachoron, or sidpid pixady, is a nonconvex uniform polychoron that consists of 120 great icosahedra, 720 pentagrammic prisms, 1200 triangular prisms, 600 truncated tetrahedra, and 120 small icosicosidodecahedra. One great icosahedron, five pentagrammic prisms, five triangular prisms, five truncated tetrahedra, and five small icosicosidodecahedra join at each vertex.
