The **small tripesic dodecahedronary dishecatonicosachoron**, or **sitpodady**, is a nonconvex fissary uniform polychoron that consists of 120 regular great icosahedra and 120 small ditrigonary icosidodecahedra. 12 great icosahedra and 20 small ditrigonary icosidodecahedra join at each vertex.

It is fissary due to the fact the edges coincide by 3, with a compound edge figure.

It can be formed as a holosnub grand hecatonicosachoron.

## Vertex coordinates[edit | edit source]

Its vertices are the same as those of its regiment colonel, the small stellated hecatonicosachoron.
