Digonal-triangular duoantiprism

The 2-3 duoantiprism is a convex isogonal polychoron that consists of 4 triangular antiprisms, 6 tetragonal disphenoids and 12 digonal disphenoids obtained through the process of alternating the 4-6 duoprism. However, it cannot be made uniform.

Vertex coordinates
The vertices of a 2-3 duoantiprism, assuming that the octahedra are regular of edge length 1, centered at the origin, are given by: with all even changes of sign, and with all odd changes of sign except for the first coordinate.
 * (0, $\sqrt{3}$/3, $\sqrt{6}$/6, $\sqrt{6}$/6)
 * (±1/2, $\sqrt{3}$/6, $\sqrt{6}$/6, $\sqrt{6}$/6)
