Icosaswirlic chiliadiacosichoron

The 2-icosahedral swirltegum, also known as the ikeswirl 1200, is an isochoric polychoron with 1200 rhombistellated hexagonal antiprisms as cells. Together with its dual, it is the second in an infinite family of icosahedral swirlchora.

Isogonal derivatives
Substitution by vertices of these following elements will produce these convex isogonal polychora:
 * Rhombistellated hexagonal antiprism (1200): 2-icosahedral swirlprism
 * Triambus (1200): 2-icosahedral swirlprism
 * Edge (720): 6-dodecahedral swirlprism
 * Vertex (720): 6-dodecahedral swirlprism
