Great ditrigonary hexacositetrishecatonicosihexacosichoron

The great ditrigonary hexacositetrishecatonicosihexacosichoron, or gidtuxthix, is a nonconvex uniform polychoron that consists of 600 octahedra, 120 icosidodecahedra, 120 small icosicosidodecahedra, 120 rhombidodecadodecahedra, 120 quasitruncated dodecadodecahedra, and 600 cubohemioctahedra. Three octahedra, three icosidodecahedra, six small icosicosidodecahedra, six rhombidodecadodecahedra, 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.
