Great snub truncatotetrahedral hecatonicosachoron

The great snub truncatotetrahedral hecatonicosachoron or gastuthi is a convex isogonal polychoron that consists of 120 truncated tetrahedra, 120 snub tetrahedra, 480 triangular-ditrigonal gyrowedges, 2160 phyllic disphenoids of three kinds, and 2880 irregular tetrahedra of two kinds. 1 snub tetrahedron, 1 truncated tetrahedron, 3 triangular-ditrigonal gyrowedges, 6 phyllic disphenoids, and 8 irregular tetrahedra join at each vertex. However, it cannot be made scaliform.
