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.

Vertex coordinates
The vertices of a small prismatodecachoric prism of edge length 1 are given by :
 * ±(0, 0, 0, ±1, ±1/2),
 * ±(0, 0, ±$\sqrt{2}$/2, ±1/2, ±1/2),
 * ±(0, $\sqrt{2}$/3, –$\sqrt{5}$/3, 0, ±1/2),
 * ±(0, $\sqrt{3}$/3, $\sqrt{6}$/6, ±1/2, ±1/2),
 * ±($\sqrt{3}$/4, –$\sqrt{6}$/4, 0, 0, ±1/2),
 * ±($\sqrt{3}$/4, $\sqrt{10}$/12, –$\sqrt{6}$/3, 0, ±1/2),
