Great retroditrigonary hexacositrishecatonicosachoron

The great retroditrigonary hexacositrishecatonicosachoron, or girdtixthi, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra, 120 great icosicosidodecahedra, 120 quasitruncated dodecadodecahedra, and 600 cubohemioctahedra. Two great ditrigonary icosidodecahedra, six great icosicosidodecahedra, twelve quasitruncated dodecadodecahedra, and six cubohemioctahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the rectified small ditrigonary hexacosihecatonicosachoron.
