Icosidihedral enneacosihexecontachoron

The icosidihedral enneacosihexecontachoron is a convex isochoric polychoron with 960 identical cells. It can be obtained as the dual of the antiwedged bitetratetrahedral diacositetracontachoron.

Each cell of this polychoron has chiral trigonal pyramidal symmetry, with 1 triangle-symmetry octadecagon, 3 enneagons, 9 tetragons, and 9 triangles for faces.

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Unnamed cell (960): Antiwedged bitetratetrahedral diacositetracontachoron
 * Vertex (240): Bitetrahedral diacositetracontachoron
 * Vertex (720): Snub bitetrahedral diacositetracontachoron
