Hexecontafold icosaswirlchoron

The hexecontafold icosaswirlchoron is an isogonal polychoron with 1200 triangular antiprisms, 1800 rhombic disphenoids and 720 vertices. It is the sixth in an infinite family of isogonal icosahedral swirlchora.

Vertex coordinates
Coordinates for the vertices of a hexecontafold icosaswirlchoron of circumradius 1, centered at the origin, are given by: along with 72°, 144°, 216° and 288° rotations in the xy axis of: where k is an integer from 0 to 29.
 * ±(0, 0, sin(kπ/30), cos(kπ/30)),
 * ±(cos(kπ/30), sin(kπ/30), 0, 0),
 * ±(2sin(kπ/30)/$\sqrt{10+2√5}$, 2cos(kπ/30)/$\sqrt{10+2√5}$, 2cos(kπ/30)/$\sqrt{10-2√5}$, 2sin(kπ/30)/$\sqrt{10-2√5}$),
