Digonal-square duoantiprism

The 2-4 duoantiprism is a convex isogonal polychoron that consists of 4 square antiprisms, 8 tetragonal disphenoids and 16 digonal disphenoids obtained through the process of alternating the 4-8 duoprism. However, it cannot be made uniform.

Vertex coordinates
The vertices of a 2-4 duoantiprism, assuming that the square antiprisms are regular of edge length 1, centered at the origin, are given by:
 * (0, ±$\sqrt{2}$/2, $\sqrt$/4, $\sqrt$/4)
 * (0, ±$\sqrt{2}$/2, -$\sqrt$/4, -$\sqrt$/4)
 * (±$\sqrt{2}$/2, 0, $\sqrt$/4, $\sqrt$/4)
 * (±$\sqrt{2}$/2, 0, -$\sqrt$/4, -$\sqrt$/4)
 * (±1/2, ±1/2, $\sqrt$/4, -$\sqrt$/4)
 * (±1/2, ±1/2, -$\sqrt$/4, $\sqrt$/4)
