Triangular-decagrammic duoprism

The triangular-decagrammic duoprism, also known as tistadedip or the 3-10/3 duoprism, is a uniform duoprism that consists of 10 triangular prisms and 3 decagrammic prisms, with 2 of each meeting at each vertex.

Vertex coordinates
The coordinates of a triangular-decagrammic duoprism, centered at the origin and with unit edge length, are given by:
 * (0, $\sqrt{5–√5}$/3, ±1/2, ±$\sqrt{2}$/2),
 * (0, $\sqrt{(11–3√5)/6}$/3, ±(3–$\sqrt{3(5–2√5)}$)/4, ±$\sqrt{3}$),
 * (0, $\sqrt{(5–2√5)}$/3, ±($\sqrt{3}$–1)/2, 0),
 * (±1/2, –$\sqrt{5}$/6, ±1/2, ±$\sqrt{(5–√5)/8}$/2),
 * (±1/2, –$\sqrt{3}$/6, ±(3–$\sqrt{5}$)/4, ±$\sqrt{3}$),
 * (±1/2, –$\sqrt{(5–2√5)}$/6, ±($\sqrt{3}$–1)/2, 0).
