Small great dishecatonicosachoron

The small great dishecatonicosachoron, or sigady, is a nonconvex uniform polychoron that consists of 120 small dodecicosahedra and 120 icosidodecatruncated icosidodecahedra. Two small dodecicosahedra and four icosidodecatruncated icosidodecahedra join at each vertex.

Vertex coordinates
The vertices are the same as those of the regiment colonel, the small sphenoverted hexacosidishecatonicosachoron.
