Small quasidisprismatohexacosihecatonicosachoron

The small quasidisprismatohexacosihecatonicosachoron, or saquid paxhi, is a nonconvex fissary uniform polychoron that consists of 600 regular tetrahedra, 120 regular dodecahedra, 1200 triangular prisms, and 720 pentagonal prisms. 4 tetrahedra, 4 dodecahedra, 12 triangular prisms, and 12 pentagonal prisms join at each vertex. It is the result of pushing the cells of either a hecatonicosachoron or a hexacosichoron inwards.

It is fissary as vertices coincide by four, producing a compound vertex figure; in addition, edges coincide by two.

It is in the same regiment as the small ditetrahedronary hexacosihecatonicosachoron.
