Grand ditetrahedronary cubidishecatonicosachoron

The grand ditetrahedronary cubidishecatonicosachoron, or gadtacady, is a nonconvex uniform polychoron that consists of 120 great icosidodecahedra, 600 cubes, and 120 quasirhombicosidodecahedra. Six great icosidodecahedra, eight cubes, and twelve quasirhombicosidodecahedra join at each vertex.
