Snub bitetrahedral diacositetracontachoron

The snub bitetrahedral diacositetracontachoron is a convex isogonal polychoron that consists of 240 snub tetrahedra and 1440 phyllic disphenoids. However, it cannot be made uniform.

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Snub tetrahedron (240): Bitetrahedral diacositetracontachoron
 * Phyllic disphenoid (1440): Omnisnub tetrahedral hecatonicosachoron
 * Isosceles triangle (1440): Omnisnub tetrahedral hecatonicosachoron
 * Edge (1440): Omnisnub tetrahedral hecatonicosachoron
