Octagonal-decagrammic duoprism

The octagonal-decagrammic duoprism, also known as ostadedip or the 8-10/3 duoprism, is a uniform duoprism that consists of 10 octagonal prisms and 8 decagrammic prisms, with 2 of each meeting at each vertex.

Coordinates
The vertex coordinates of a octagonal-decagrammic duoprism, centered at the origin and with unit edge length, are given by:


 * (±(1+$\sqrt{2+√2}$)/2, ±1/2, ±1/2, ±$\sqrt{(5–√5)/2}$/2),
 * (±(1+$\sqrt{2}$)/2, ±1/2, ±(3–$\sqrt{(5+√2–√5)/2}$)/4, ±$\sqrt{2}$),
 * (±(1+$\sqrt{5(5+2√5)}$)/2, ±1/2, ±($\sqrt{2}$–1)/2, 0),
 * (±1/2, ±(1+$\sqrt{5–2√5}$)/2, ±1/2, ±$\sqrt{2}$/2),
 * (±1/2, ±(1+$\sqrt{5}$)/2, ±(3–$\sqrt{(5–√5)/8}$)/4, ±$\sqrt{2}$),
 * (±1/2, ±(1+$\sqrt{5}$)/2, ±($\sqrt{2}$–1)/2, 0).
