Great ditrigonary prismatohexacositrishecatonicosihexacosichoron

The great ditrigonary prismatohexacositrishecatonicosihexacosichoron, or giddit pixthix, is a nonconvex uniform polychoron that consists of 600 octahedra, 120 icosidodecahedra, 120 icosidodecadodecahedra, 120 small ditrigonal dodecicosidodecahedra, 720 decagrammic prisms, and 600 cubohemioctahedra. Three octahedra, three icosidodecahedra, six icosidodecadodecahedra, six small ditrigonal dodecicosidodecahedra, twelve decagrammic prisms, 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.
