Great dishexacosidishecatonicosachoron

{{Infobox polytope The great dishexacosidishecatonicosachoron, or gadixady, is a nonconvex uniform polychoron that consists of 600 regular tetrahedra, 120 regular dodecahedra, 600 truncated tetrahedra, and 120 truncated icosahedra. 1 tetrahedron, 1 dodecahedron, 3 truncated tetrahedra, and 3 truncated icosahedra join at each vertex.
