Notched heptacosicosachoron

The notched heptacosicosachoron is a convex isochoric polychoron with 720 mirror-symmetric notches as cells.

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Mirror-symmetric notch (720): Snub ambotetrahedral hecatonicosachoron
 * Scalene triangle (1440): Omnisnub tetrahedral hecatonicosachoron
 * Edge (1440): Omnisnub tetrahedral hecatonicosachoron
 * Vertex (120): Hexacosichoron
