The **small ditetrahedrofissary dishecatonicosachoron**, or **sadtifady**, is a nonconvex fissary uniform polychoron that consists of 120 icosidodecahedra and 120 small dodecicosidodecahedra. 6 icosidodecahedra and 12 small dodecicosidodecahedra join at each vertex.

It is fissary with vertices coinciding by 3, and edges coinciding by two.

## Vertex coordinates[edit | edit source]

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