Great tritrigonary hecatonicosiprismatodishecatonicosihexacosichoron

The great tritrigonary hecatonicosiprismatodishecatonicosihexacosichoron, or git thipdahix, is a nonconvex uniform polychoron that consists of 600 tetrahedra, 120 truncated great icosahedra, 120 quasirhombicosidodecahedra, 720 decagrammic prisms, and 120 great quasitruncated icosidodecahedra. One tetrahedron, three truncated great icosahedra, three quasirhombicosidodecahedra, six decagrammic prisms, and six great quasitruncated icosidodecahedra join at each vertex.

It also has compound of five cubes as pseudofacets.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the great tritrigonary hexacositrishecatonicosachoron.
