Great ditrigonary trishecatonicosicubidishexacosichoron

The great ditrigonary trishecatonicosicubidishexacosichoron, or giddit thicdex, is a nonconvex uniform polychoron that consists of 600 cubes (some of which lie in the same hyperplane, forming 120 compound of five cubes), 600 octahedra, 120 icosidodecahedra, 120 rhombidodecadodecahedra, 120 small icosicosidodecahedra, and 600 cubohemioctahedra. Four cubes (or two compounds), three octahedra, three icosidodecahedra, six rhombidodecadodecahedra, six small icosicosidodecahedra, and six cubohemioctahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the rectified small ditrigonary hexacosihecatonicosachoron.
