Decagonal-decagrammic duoprism

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

This polychoron can be alternated into the great duoantiprism, which can be made uniform.

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