Hexagonal double gyroantiprismoid

The hexagonal double antiprismoid is a convex isogonal polychoron and the third member of the double antiprismoids that consists of 24 hexagonal antiprisms, 72 tetragonal disphenoids, 144 rhombic disphenoids and 288 sphenoids obtained as the convex hull of two orthogonal hexagonal-hexagonal duoantiprisms. However, it cannot be made uniform. Together with its dual, it is the first in an infinite family of hexagonal antiprismatic swirlchora.

Vertex coordinates
The vertices of a hexagonal double antiprismoid, assuming that the hexagonal antiprisms are regular of edge length 1, centered at the origin, are given by:
