Dodecaswirlic heptacosicosachoron

The dodecaswirlic heptacosicosachoron, also known as the doeswirl 720, is an isochoric polychoron with 720 rhombistellated decagonal antiprisms as cells. It is the sixth in an infinite family of isochoric dodecahedral swirlchora.

Each cell of this polychoron has a chiral pentagonal prismatic symmetry, with 2 pentambi (pentagonal-symmetric decagons), 5 rhombi, and 10 isosceles triangles for faces.

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Rhombistellated decagonal antiprism (720): Hexecontafold icosaswirlchoron
 * Pentambus (720): Hexecontafold icosaswirlchoron
 * Edge (1200): Hexecontafold dodecaswirlchoron
 * Vertex (1200): Hexecontafold dodecaswirlchoron
