Grand ditetrahedronary prismatohexacosicubihecatonicosachoron

The grand ditetrahedronary prismatohexacosicubihecatonicosachoron, or gadtapaxchi, is a nonconvex uniform polychoron that consists of 600 tetrahedra, 600 cubes (lying in the same hyperplanes, forming 120 compounds of five cubes), 720 pentagrammic prisms, and 120 great dodecicosidodecahedra. Four tetrahedra, eight cubes (or four compounds), twelve pentagrammic prisms, and twelve great dodecicosidodecahedra join at each vertex.
