The cantellated 1 22 polytope or sram, also called the cantellated 122 polytope, is a convex uniform polypeton. It consists of 54 small birhombated penteracts, 72 small birhombidodecatera, and 720 triangular duoprismatic prisms. 4 small birhombated penteracts, 1 small birhombidodecateron, and 2 triangular duoprismatic prisms join at each vertex. As the name suggests, it is the cantellation of the pentacontatetrapeton.
