The Uniform Polyhedron $U_{70}$ whose Dual is the Great Dodecahemidodecacron. It has Wythoff Symbol ${\textstyle{5\over 3}}\,{\textstyle{5\over 2}}\,\vert\,{\textstyle{5\over 3}}$. Its faces are $12\{{\textstyle{5\over 2}}\}+6\{{\textstyle{10\over 3}}\}$. Its Circumradius for unit edge length is

\begin{displaymath}
R=\phi^{-1},
\end{displaymath}

where $\phi$ is the Golden Ratio.
