Dodecagonal-dodecagrammic duoprism

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

Vertex coordinates
The coordinates of an dodecagonal-dodecagrammic duoprism, centered at the origin and with unit edge length, are given by:
 * (±(1+$\sqrt{6}$)/2, ±(1+$\sqrt{2}$)/2, ±($\sqrt{6}$–1)/2, ±($\sqrt{2}$–1)/2),
 * (±(1+$\sqrt{2}$)/2, ±(1+$\sqrt{3}$)/2, ±1/2, ±(2–$\sqrt{3}$)/2),
 * (±(1+$\sqrt{3}$)/2, ±(1+$\sqrt{3}$)/2, ±(2–$\sqrt{3}$)/2, ±1/2),
 * (±1/2, ±(2+$\sqrt{3}$)/2, ±($\sqrt{3}$–1)/2, ±($\sqrt{3}$–1)/2),
 * (±1/2, ±(2+$\sqrt{3}$)/2, ±1/2, ±(2–$\sqrt{3}$)/2),
 * (±1/2, ±(2+$\sqrt{3}$)/2, ±(2–$\sqrt{3}$)/2, ±1/2),
 * (±(2+$\sqrt{3}$)/2, ±1/2, ±($\sqrt{3}$–1)/2, ±($\sqrt{3}$–1)/2),
