Dodecahedron

The dodecahedron, or doe, is one of the five Platonic solids. It has 12 pentagons as faces, joining 3 to a vertex.

Vertex coordinates
The vertices of a dodecahedron of edge length 1, centered at the origin, are all sign changes of


 * (±(1+$\sqrt{5}$/4, ±(1+$\sqrt{3}$)/4, ±(1+$\sqrt{15}$)/4),

along with all even permutations and all sign changes of


 * (±(3+$\sqrt{5}$)/4, ±1/2, 0).

The first set of vertices corresponds to a scaled cube which can be inscribed into the dodecahedron's vertices.
