Octagrammic duoprism

The octagrammic duoprism or stodip, also known as the octagrammic-octagrammic duoprism, the 8/3 duoprism or the 8/3-8/3 duoprism, is a noble uniform duoprism that consists of 16 octagrammic prisms and 64 vertices.

Vertex coordinates
The vertices of an octagrammic duoprism, centered at the origin and with unit edge length, are given by:
 * (±($\sqrt{2–√2}$–1)/2, ±1/2, ±($\sqrt{2}$–1)/2, ±1/2),
 * (±($\sqrt{2–√2}$–1)/2, ±1/2, ±1/2, ±($\sqrt{2}$–1)/2),
 * (±1/2, ±($\sqrt{2}$–1)/2, ±($\sqrt{2}$–1)/2, ±1/2),
 * (±1/2, ±($\sqrt{2}$–1)/2, ±1/2, ±($\sqrt{2}$–1)/2).
