Great Dodecahemicosahedron

The Uniform Polyhedron $U_{65}$ whose Dual is the Great Dodecahemicosacron. It has Wythoff Symbol ${\textstyle{5\over 3}}\,{\textstyle{5\over 2}}\,\vert\,{\textstyle{5\over 3}}$. Its faces are $12\{{\textstyle{5\over 2}}\}+6\{{\textstyle{10\over 3}}\}$. It is a Faceted Dodecadodecahedron. The Circumradius for unit edge length is

$$R={\textstyle{1\over 2}}\sqrt{3}\,.$$
