Great dipentary hexacosihecatonicosihexacositrishecatonicosachoron

The great dipentary hexacosihecatonicosihexacositrishecatonicosachoron, or gidpixhixthi, is a nonconvex uniform polychoron that consists of 120 great icosahedra, 120 great dodecahedra, 600 cuboctahedra, 120 rhombidodecadodecahedra, 600 truncated tetrahedra, and 120 truncated great icosahedra. One great icosahedron, one great dodecahedron, five cuboctahedra, five rhombidodecadodecahedra, five truncated tetrahedra, and five truncated great icosahedra join at each vertex.

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