Great tritrigonary prismatotetrishecatonicosachoron

The great tritrigonary prismatotetrishecatonicosachoron, or getit pothi, is a nonconvex uniform polychoron that consists of 120 ditrigonary dodecadodecahedra, 120 great dodecicosahedra, 120 great rhombidodecahedra, 720 pentagonal prisms, and 120 truncated great icosahedra. One ditrigonary dodecadodecahedron, three great dodecicosahedra, three great rhombidodecahedra, three pentagonal prisms, and three truncated great icosahedra join at each vertex.

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