Decagrammic duoprism

The decagrammic duoprism or stadidip, also known as the decagrammic-decagrammic duoprism, the 10/3 duoprism or the 10/3-10/3 duoprism, is a noble uniform duoprism that consists of 20 decagrammic prisms and 100 vertices.

Vertex coordinates
The vertices of a decagrammic duoprism, centered at the origin and with unit edge length, are given by:


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