Great ditrigonary tetrishecatonicosidishexacosichoron

The great ditrigonary tetrishecatonicosidishexacosichoron, or gidtuthiddix, is a nonconvex uniform polychoron that consists of 120 ditrigonary dodecadodecahedra, 600 octahedra, 120 icosidodecahedra, 120 small icosicosidodecahedra, 120 quasitruncated dodecadodecahedra, and 600 cubohemioctahedra. Two ditrigonary dodecadodecahedra, three octahedra, three icosidodecahedra, six small 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.
