Great rhombated pentachoron

The great rhombated pentachoron, or grip, also commonly called the cantitruncated 5-cell, is a convex uniform polychoron that consists of 10 triangular prisms, 5 truncated tetrahedra, and 5 truncated octahedra. 1 triangular prism, 1 truncated tetrahedron, and 2 truncated octahedra join at each vertex. As one of its names suggests, it can be obtained by cantitruncating the pentachoron.
