Ditrigonal Dodecadodecahedron

The Uniform Polyhedron $U_{41}$, also called the Ditrigonal Dodecahedron, whose Dual Polyhedron is the Medial Triambic Icosahedron. It has Wythoff Symbol $3\,\vert\,{\textstyle{5\over 3}}\,5$. Its faces are $12\{{\textstyle{5\over 2}}\}+12\{5\}$. It is a Faceted version of the Small Ditrigonal Icosidodecahedron. The Circumradius for unit edge length is

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