Small rhombated pentachoron

The small rhombated pentachoron, or srip, also commonly called the cantellated 5-cell, is a convex uniform polychoron that consists of 5 regular octahedra, 10 triangular prisms, and 5 cuboctahedra. 1 octahedron, 2 triangular prisms, and 2 cuboctahedra join at each vertex.
