Small prismatodecachoric prism

The small prismatodecachoric prism or spiddip is a prismatic uniform polyteron that consists of 2 small prismatodecachora, 10 tetrahedral prisms, and 20 triangular-square duoprisms. 1 small prismatodecachoron, 2 tetrahedral prisms, and 6 triangular-square duoprisms join at each vertex. As the name suggests, it can be obtained as a prism based on the small prismatodecachoron, which also makes it a convex segmentoteron.

Vertex coordinates
The vertices of a small prismatodecachoric prism of edge length 1 are given by:
 * $$±\left(0,\,0,\,0,\,±1,\,±\frac12\right),$$
 * $$±\left(0,\,0,\,±\frac{\sqrt3}{2},\,±\frac12,\,±\frac12\right),$$
 * $$±\left(0,\,\frac{\sqrt6}{3},\,-\frac{\sqrt3}{3},\,0,\,±\frac12\right),$$
 * $$±\left(0,\,\frac{\sqrt6}{3},\,\frac{\sqrt3}{6},\,±\frac12,\,±\frac12\right),$$
 * $$±\left(\frac{\sqrt{10}}{4},\,-\frac{\sqrt6}{4},\,0,\,0,\,±\frac12\right),$$
 * $$±\left(\frac{\sqrt{10}}{4},\,\frac{\sqrt6}{12},\,-\frac{\sqrt3}{3},\,0,\,±\frac12\right),$$
 * $$±\left(\frac{\sqrt{10}}{4},\,\frac{\sqrt6}{12},\,\frac{\sqrt3}{6},\,±\frac12,\,±\frac12\right).$$
