Octagrammic-decagonal duoprism

The octagrammic-decagonal duoprism, also known as stodedip or the 8/3-10 duoprism, is a uniform duoprism that consists of 10 octagrammic prisms and 8 decagonal prisms, with 2 of each at each vertex.

Vertex coordinates
The coordinates of a octagrammic-decagonal duoprism, centered at the origin and with unit edge length, are given by:
 * $$\left(±\frac12,\,±\frac{\sqrt2-1}2,\,±\frac12,\,±\frac{\sqrt{5+2\sqrt5}}2\right),$$
 * $$\left(±\frac12,\,±\frac{\sqrt2-1}2,\,±\frac{3+\sqrt5}4,\,±\sqrt{\frac{5+\sqrt5}8}\right),$$
 * $$\left(±\frac12,\,±\frac{\sqrt2-1}2,\,±\frac{1+\sqrt5}2,\,0\right),$$
 * $$\left(±\frac{\sqrt2-1}2,\,±\frac12,\,±\frac12,\,±\frac{\sqrt{5+2\sqrt5}}2\right),$$
 * $$\left(±\frac{\sqrt2-1}2,\,±\frac12,\,±\frac{3+\sqrt5}4,\,±\sqrt{\frac{5+\sqrt5}8}\right),$$
 * $$\left(±\frac{\sqrt2-1}2,\,±\frac12,\,±\frac{1+\sqrt5}2,\,0\right).$$

Representations
An octagrammic-decagonal duoprism has the following Coxeter diagrams:
 * x8/3o x10o (full symmetry)
 * x5x x8/3o (H2×I2(8) symmetry, decagons as dipentagons)
