Digonal-square duoantiprism

The digonal-square duoantiprism, also known as 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 square-octagonal duoprism. However, it cannot be made uniform.

Vertex coordinates
The vertices of a digonal-square duoantiprism, assuming that the square antiprisms are uniform 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)
