Great tritrigonary trishecatonicosihexacosichoron

The great tritrigonary trishecatonicosihexacosichoron, or getit thix, is a nonconvex uniform polychoron that consists of 600 regular tetrahedra, 120 truncated great icosahedra, 120 great icosicosidodecahedra, and 120 ditrigonary dodecadodecahedra. 1 tetrahedron, 3 truncated great icosahedra, 3 great icosicosidodecahedra, and 1 ditrigonary dodecadodecahedron join at each vertex.

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