Great prismated pentacontatetrapeton

The great prismated pentacontatetrapeton or gopam, also called the runcicantitruncated 122 polytope, is a convex uniform polypeton. It consists of 54 great prismated triacontaditera, 72 great cellidodecatera, 432 great prismatodecachoric prisms, and 720 hexagonal duoprismatic prisms. 2 great prismated triacontaditera, 1 great cellidodecateron, 1 great prismatodecachoric prism, and 1 hexagonal duoprismatic prism join at each vertex. As the name suggests, it is the runcicantitruncation of the pentacontatetrapeton.
