Tetrahedral-snub tetrahedral hecatonicosachoron

The tetrahedral-snub tetrahedral hecatonicosachoron or tisthi is a convex isogonal polychoron that consists of 120 snub tetrahedra, 120 tetrahedra, 480 triangular pyramids, and 720 phyllic disphenoids. 3 snub tetrahedra, 1 tetrahedron, 4 triangular pyramids, and 6 phyllic disphenoids join at each vertex. However, it cannot be made uniform.
