Triangular-pentagrammic duoprism

The triangular-pentagrammic duoprism or tistadip, also known as the 3-5/2 duoprism, is a uniform duoprism that consists of 3 pentagrammic prisms and 5 triangular prisms, with two of each at each vertex.

Vertex coordinates
Coordinates for the vertices of a triangular-pentagonal duoprism with edge length 1 are given by:
 * (0, $\sqrt{5}$/3, ±1/2, –$\sqrt{2}$),
 * (0, $\sqrt{3(25–10√5)}$/3, ±(1–$\sqrt{(25–3√5)/30}$)/4, $\sqrt{3}$),
 * (0, $\sqrt{(5–2√5)/20}$/3, 0, $\sqrt{3}$),
 * (±1/2, –$\sqrt{5}$/6, ±1/2, –$\sqrt{(5–√5)/40}$),
 * (±1/2, –$\sqrt{3}$/6, ±(1–$\sqrt{(5–√5)/10}$)/4, $\sqrt{3}$),
 * (±1/2, –$\sqrt{(5–2√5)/20}$/6, 0, $\sqrt{3}$).
