The 2-3 duoantiwedge or tridafup is a convex scaliform polyteron and a duoantiwedge that consists of 4 triangular prismatoantiwedges and 6 square scalenes.

Vertex coordinates
Coordinates for the vertices of a 2-3 duoantiwedge of edge length 1, centered at the origin, are given by all sign changes excluding the last coordinate of:
 * (0, 1/2, 0, -$\sqrt{10}$/3, $\sqrt{3}$/12)
 * (0, 1/2, 1/2, $\sqrt{6}$/6, $\sqrt{3}$/12)
 * (1/2, 0, 0, $\sqrt{6}$/3, -$\sqrt{3}$/12)
 * (1/2, 0, 1/2, -$\sqrt{6}$/6, -$\sqrt{3}$/12)
