The Uniform Polyhedron $U_{32}$ whose Dual Polyhedron is the Small Hexagonal Hexecontahedron. It has Wythoff Symbol $\vert\,3\,3\,{\textstyle{5\over 2}}$ (Har'El 1993 gives the symbol as $\vert\,{\textstyle{5\over 2}}\,3\,3$.) Its faces are $100\{3\}+12\{{\textstyle{5\over 2}}\}$. Its Circumradius for $a=1$ is

$\displaystyle R$ $\textstyle =$ $\displaystyle {\textstyle{1\over 4}}\sqrt{13+3\sqrt{5}+\sqrt{102+46\sqrt{5}}}$  
  $\textstyle =$ $\displaystyle 1.4581903307387\ldots.$
