Great ditrigonary hecatonicosihexacosihecatonicosidishecatonicosachoron

The great ditrigonary hecatonicosihexacosihecatonicosidishecatonicosachoron, or gidthixhidy, is a nonconvex uniform polychoron that consists of 120 ditrigonary dodecadodecahedra, 600 octahedra, 120 icosidodecahedra, 120 small icosicosidodecahedra, and 120 rhombicosahedra. Two ditrigonary dodecadodecahedra, three octahedra, three icosidodecahedra, six small icosicosidodecahedra, and six rhombicosahedra join at each vertex.

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