Small rhombicosidodecahedron atop truncated dodecahedron

Small rhombicosidodecahedron atop truncated dodecahedron, or sridatid, is a CRF segmentochoron (designated K-4.159 on Richard Klitzing's list). As the name suggests, it consists of a small rhombicosidodecahedron and a truncated dodecahedron as bases, connected by 30 triangular prisms, 20 octahedra, and 12 pentagonal cupolas.

It can be obtained as a small rhombicosidodecahedron-first cap of the small rhombated hecatonicosachoron.

Vertex coordinates
