Octahedral duoprism

The octahedral duoprism or octdip is a convex uniform duoprism that consists of 16 triangular-octahedral duoprisms. It is the prism product of two octahedra. It is the first in an infinite family of isopetic digonal hosohedral swirlpeta.

Vertex coordinates
The vertices of an octahedral duoprism of edge length 1 are given by all permutations of the first three coordinates and all permutations of the last three coordinates of:
 * (±$\sqrt{2}$/2, 0, 0, ±$\sqrt{2}$/2, 0, 0).
