Small spinoprismatodishecatonicosachoron

The small spinoprismatodishecatonicosachoron, or snappady, is a nonconvex uniform polychoron that consists of 120 dodecahedra, 720 pentagonal prisms, and 120 small rhombidodecahedra. One dodecahedron, three pentagonal prisms, and three small rhombidodecahedra join at each vertex.

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