Prismatotruncated pentacontatetrapeton

The prismatotruncated pentacontatetrapeton or patom, also called the runcitruncated 122 polytope, is a convex uniform polypeton. It consists of 54 prismatotruncated demipenteracts, 72 cellirhombidodecatera, 432 prismatorhombated pentachoric prisms, and 720 triangular duoprismatic prisms. 2 prismatotruncated demipenteracts, 1 cellirhombidodecateron, 4 prismatorhombated pentachoric prisms, and 1 triangular duoprismatic prism join at each vertex. As the name suggests, it is the runcitruncation of the pentacontatetrapeton.
