Quasiprismatohecatonicosachoron

The quasiprismatohecatonicosachoron, or quiphi, is a nonconvex uniform polychoron that consists of 120 small stellated dodecahedra and 720 pentagrammic prisms. 2 small stellated dodecahedra and 10 pentagrammic prisms join at each vertex.

It is in the same regiment as the rectified great faceted hexacosichoron.

A double cover of this polychoron can be formed by pushing the cells of the grand stellated hecatonicosachoron inward.

Vertex coordinates
Its vertices are the same as those of its regiment colonel, the rectified great faceted hexacosichoron.
