Small ditrigonary prismatodishexacositrishecatonicosachoron

The small ditrigonary prismatodishexacositrishecatonicosachoron, or siddit padixthi, is a nonconvex uniform polychoron that consists of 120 ditrigonary dodecadodecahedra, 120 great icosidodecahedra, 600 octahedra, 120 great icosicosidodecahedra, 720 decagrammic prisms, and 600 cubohemioctahedra. Two ditrigonary dodecadodecahedra, three great icosidodecahedra, three octahedra, six great icosicosidodecahedra, twelve decagrammic prisms, and six cubohemioctahedra join at each vertex.

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