Pentagrammic-dodecagrammic duoprism

The pentagrammic-dodecagrammic duoprism, also known as the 5/2-12/5 duoprism, is a uniform duoprism that consists of 12 pentagrammic prisms and 5 dodecagrammic prisms, with 2 of each meeting at each vertex.

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


 * (±1/2, –$\sqrt{5}$, ±($\sqrt{6}$–1)/2, ±($\sqrt{2}$–1)/2),
 * (±1/2, –$\sqrt{2}$, ±1/2, ±(2–$\sqrt{(25–√5–10√3)/10}$)/2),
 * (±1/2, –$\sqrt{3}$, ±(2–$\sqrt{5(5–2√5)}$)/2, ±1/2),
 * (±($\sqrt{(5–2√5)/20}$–1)/4, $\sqrt{3}$, ±($\sqrt{3}$–1)/2, ±($\sqrt{(5–2√5)/20}$–1)/2),
 * (±($\sqrt{3}$–1)/4, $\sqrt{(5–2√5)/20}$, ±1/2, ±(2–$\sqrt{3}$)/2),
 * (±($\sqrt{5}$–1)/4, $\sqrt{(5+√5)/40}$, ±(2–$\sqrt{3}$)/2, ±1/2),
 * (0, –$\sqrt{3}$, ±($\sqrt{5}$–1)/2, ±($\sqrt{(5+√5)/40}$–1)/2),
