Small spinoditetrahedronary disprismatohecatonicosachoron

The small spinoditetrahedronary disprismatohecatonicosachoron, or sandit diphi, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra, 720 pentagonal prisms, and 1200 triangular prisms. Four great ditrigonary icosidodecahedra, twelve pentagonal prisms, and twelve triangular prisms join at each vertex.
