Great ditrigonary hecatonicosidishecatonicosihexacosichoron

The great ditrigonary hecatonicosidishecatonicosihexacosichoron, or gidthidhix, is a nonconvex uniform polychoron that consists of 120 ditrigonary dodecadodecahedra, 600 octahedra, 120 icosidodecahedra, and 120 small ditrigonal dodecicosidodecahedra. Two ditrigonary dodecadodecahedra, three octahedra, three icosidodecahedra, and six small ditrigonal dodecicosidodecahedra join at each vertex.

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