Triangular duoantifastegium

The digonal-triangular duoantiwedge or triddaf, also known as the 2-3 duoantiwedge, is a convex scaliform polyteron and a duoantiwedge that consists of 4 triangular antifastegiums and 6 square scalenes.

Vertex coordinates
Coordinates for the vertices of a digonal-triangular duoantiwedge of edge length 1, centered at the origin, are given by:
 * (0, $\sqrt{10}$/3, 0, ±1/2, $\sqrt{3}$/12),
 * (±1/2, -$\sqrt{6}$/6, 0, ±1/2, $\sqrt{3}$/12),
 * (0, -$\sqrt{6}$/3, ±1/2, 0, -$\sqrt{3}$/12),
 * (±1/2, $\sqrt{6}$/6, ±1/2, 0, -$\sqrt{3}$/12).
