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 cubes and 4 decagrammic prisms, with 2 of each meeting at each vertex.

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