Small snub truncatotetrahedral hecatonicosachoron

The small snub truncatotetrahedral hecatonicosachoron or sestuthi is a convex isogonal polychoron that consists of 120 truncated tetrahedra, 120 snub tetrahedra, 480 chiral triangular antipodiums, 480 triangular-ditrigonal gyrowedges, and 720 phyllic disphenoids. 1 snub tetrahedron, 1 truncated tetrahedron, 2 triangular antipodiums, 3 triangular-ditrigonal gyrowedges, and 2 pyllic disphenoids join at each vertex. However, it cannot be made scaliform.
