Small ditetrahedronary dishecatonicosachoron

The small ditetrahedronary dishecatonicosachoron, or siddatady, is a nonconvex uniform polychoron that consists of 120 regular dodecahedra and 120 ditrigonary dodecadodecahedra. 4 ditrigonary dodecadodecahedra and 4 dodecahedra join at each vertex.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the small ditetrahedronary hexacosihecatonicosachoron.
