Square-decagrammic duoprism

The square-decagrammic duoprism, also known as sistadedip or the 4-10/3 duoprism, is a uniform duoprism that consists of 10 cube s and 4 decagrammic prism s, with 2 of each meeting at each vertex.

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


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