Great tritrigonary prismatotrishecatonicosihexacosichoron

The great tritrigonary prismatotrishecatonicosihexacosichoron, or getit pithix, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra, 600 cubohemioctahedra, 120 great dodecicosahedra, 720 pentagonal prisms, and 120 quasitruncated great stellated dodecahedra. One great ditrigonary icosidodecahedron, three cubohemioctahedra, three great dodecicosahedra, three pentagonal prisms, and three quasitruncated great stellated dodecahedra join at each vertex.

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