Great snub rhombatotetrahedral hecatonicosachoron

The great snub rhombatotetrahedral hecatonicosachoron or giserthi is a convex isogonal polychoron that consists of 120 rhombitetratetrahedra, 120 snub tetrahedra, 480 chiral triangular antipodiums, 720 digonal-rectangular gyrowedges, 1440 phyllic disphenoids of two kinds, and 1440 irregular tetrahedra. 1 snub tetrahedron, 1 rhombitetratetrahedron, 2 triangular antipodiums, 3 digonal-rectangular gyrowedges, 4 phyllic disphenoids, and 4 irregular tetrahedra join at each vertex. However, it cannot be made scaliform.
