Grand intercepted ditetrahedronary disprismatohecatonicosachoron

The grand intercepted ditetrahedronary disprismatohecatonicosachoron, or gand tadiphi, is a nonconvex uniform polychoron that consists of 120 small ditrigonary icosidodecahedra, 720 pentagrammic prisms, and 1200 triangular prisms. Four small ditrigonary icosidodecahedra, twelve pentagrammic prisms, and twelve triangular prisms join at each vertex.
