Ditetrahedronary disprismatohecatonicosachoron

The ditetrahedronary disprismatohecatonicosachoron, or dittadphi, is a nonconvex uniform polychoron that consists of 120 ditrigonary dodecadodecahedra, 720 pentagrammic prisms, and 720 pentagonal prisms. Four ditrigonary dodecadodecahedra, twelve pentagrammic prisms, and twelve pentagonal prisms join at each vertex.
