Triangular duoprism

The 3-3 duoprism is a noble uniform duoprism that consists of 6 triangular prisms and 9 vertices. It is the simplest possible duoprism and is also the 6-2 gyrochoron. The 3-3 duoprism, along with its dual, is the first in a series of triangular dihedral swirlchora.

Vertex coordinates
The vertices of a 3-3 duoprism of edge length 1, centered at the origin, are given by:
 * (0, $\sqrt{3}$/3, 0, $\sqrt{3}$/3)
 * (0, $\sqrt{3}$/3, ±1/2, -$\sqrt{3}$/6)
 * (±1/2, -$\sqrt{3}$/6, 0, $\sqrt{3}$/3)
 * (±1/2, -$\sqrt{3}$/6, ±1/2, -$\sqrt{3}$/6)
