Small demirhombated icosiheptaheptacontadipeton

The small demirhombated icosiheptaheptacontadipeton or shorjak, also called the demicantellated 221 polytope, is a convex uniform polypeton. It consists of 27 prismatotruncated demipenteracts, 27 truncated demipenteracts, 72 small rhombated hexatera, and 216 truncated pentachoric prisms. 3 prismatotruncated demipenteracts, 1 truncated demipenteract, 1 small rhombated hexateron, and 2 truncated pentachoric prisms join at each vertex. As the name suggests, it is the demicantellation of the icosiheptaheptacontadipeton.
