Square-tetrahedral duoantiprism

The square-tetrahedral duoantiprism is a convex isogonal polyteron that consists of 8 tetrahedral antiprisms, 6 digonal-square duoantiprisms, 32 triangular scalenes obtained through the process of alternating the octagonal-cubic duoprism. However, it cannot be made uniform.

Vertex coordinates
The vertices of a square-tetrahedral duoantiprism, assuming that the edge length differences are minimized, centered at the origin, are given by: with all even changes of sign of the last three coordinates, and with all odd changes of sign of the last three coordinates.
