Grand rhombic small hexacosihecatonicosachoron

The grand rhombic small hexacosihecatonicosachoron, or garsixhi, is a nonconvex uniform polychoron that consists of 600 cubohemioctahedra and 120 great rhombicosidodecahedra. Two cubohemioctahedra and four great rhombicosidodecahedra join at each vertex.

Vertex coordinates
The vertices are the same as those of the regiment colonel, the small rhombated hexacosichoron.
