Triangular-gyroprismatic enneacontahexachoron

The triangular-antiprismatic enneacontahexachoron, also known as the octswirl 96, is a noble polychoron with 96 triangular antiprisms and 72 vertices. Together with its dual, it is the third in an infinite family of cubic swirlchora and also the second in an infinite family of octahedral swirlchora.

Vertex coordinates
Coordinates for the vertices of a triangular-antiprismatic enneacontahexachoron of circumradius 1, centered at the origin, are given by all permutations and sign changes of: defining an icositetrachoron, along with reflections through the x=y and z=w hyperplanes and with all sign changes of: along with reflections through the x=y and z=w hyperplanes and with all even sign changes of: along with reflections through the x=y and z=w hyperplanes and with all odd sign changes of:
 * (0, 0, 0, 1)
 * (1/2, 1/2, 1/2, 1/2)
 * (0, 0, 1/2, $\sqrt{3}$/2)
 * (1/2, $\sqrt{3}$/2, 0, 0)
