Elongated triangular orthobicupola

The elongated triangular orthobicupola, or etobcu, is one of the 92 Johnson solids (J35). It consists of 2+6 triangles and 3+3+6 squares. It can be constructed by inserting a hexagonal prism between the two halves of the triangular orthobicupola.

Vertex coordinates
An elongated triangular orthobicupola of edge length 1 has the following vertices:
 * $$\left(±\frac12,\,±\frac{\sqrt3}{2},\,±\frac12\right),$$
 * $$\left(±1,\,0,\,±\frac12\right),$$
 * $$\left(±\frac12,\,-\frac{\sqrt3}{6},\,±\frac{3+2\sqrt3}{6}\right),$$
 * $$\left(0,\,\frac{\sqrt3}{3},\,±\frac{3+2\sqrt3}{6}\right).$$
