Grand ditetrahedronary cubihexacosidishecatonicosachoron

The grand ditetrahedronary cubihexacosidishecatonicosachoron, or gadtacaxady, is a nonconvex uniform polychoron that consists of 120 great stellated dodecahedra, 600 tetrahedra, 600 cubes (lying in the same hyperplanes, forming 120 compounds of five cubes), and 120 quasirhombicosidodecahedra. Four great stellated dodecahedra, four tetrahedra, eight cubes (or four compounds), and twelve quasirhombicosidodecahedra join at each vertex.
