The great dodecahemicosahedron is the uniform polyhedron with Maeder index 65 (Maeder 1997), Wenninger index 102 (Wenninger 1989), Coxeter
index 81 (Coxeter et al. 1954), and Har'El index 70 (Har'El 1993). It has
Wythoff symbol 
and its faces are 
. It is a faceted dodecadodecahedron.
The great dodecahemicosahedron is implemented in the Wolfram Language as UniformPolyhedron[102],
UniformPolyhedron["GreatDodecahemicosahedron"],
UniformPolyhedron[
"Coxeter",
81
],
UniformPolyhedron[
"Kaleido",
70
],
UniformPolyhedron[
"Uniform",
65
],
or UniformPolyhedron[
"Wenninger",
102
].
It is also implemented in the Wolfram
Language as PolyhedronData["GreatDodecahemicosahedron"].
The convex hull is a regular icosidodecahedron.
Its skeleton is the dodecadodecahedral graph.
The circumradius for unit edge length is 
.
Its dual is the great dodecahemicosacron.
