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:
 * (±1/2, ±$\sqrt{2}$/2, ±1/2),
 * (±1, 0, ±1/2),
 * (±1/2, –$\sqrt{2}$/6, ±(3+2$\sqrt{2}$)/6),
 * (0, $\sqrt{2}$/3, ±(3+2$\sqrt{2}$)/6).
