Octagrammic-decagrammic duoprism

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

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