Great ditrigonary hexacositrishecatonicosachoron

The great ditrigonary hexacositrishecatonicosachoron, or gidtixthi, is a nonconvex uniform polychoron that consists of 120 great ditrigonary icosidodecahedra, 120 small ditrigonal dodecicosidodecahedra, 120 icosidodecadodecahedra, and 600 octahemioctahedra. Two great ditrigonary icosidodecahedra, six small ditrigonal dodecicosidodecahedra, six icosidodecadodecahedra, and six octahemioctahedra join at each vertex.

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