Icositruncated Dodecadodecahedron

The Uniform Polyhedron $U_{45}$ also called the Icosidodecatruncated Icosidodecahedron whose Dual Polyhedron is the Tridyakis Icosahedron. It has Wythoff Symbol $3\,{\textstyle{5\over 3}}\,5\,\vert$. Its faces are $20\{6\}+12\{10\}+12\{{\textstyle{10\over 3}}\}$. Its Circumradius for unit edge length is

$$R=2.$$
