The great snub dodecicosidodecahedron is the uniform polyhedron with Maeder index 64 (Maeder 1997), Wenninger index 115 (Wenninger 1989), Coxeter index 80 (Coxeter et al. 1954), and Har'El index 69 (Har'El 1993). It has Wythoff symbol and its faces are .
The great snub dodecicosidodecahedron is implemented in the Wolfram Language as UniformPolyhedron[115], UniformPolyhedron["GreatSnubDodecicosidodecahedron"], UniformPolyhedron["Coxeter", 80], UniformPolyhedron["Kaleido", 69], UniformPolyhedron["Uniform", 64], or UniformPolyhedron["Wenninger", 115]. It is also implemented in the Wolfram Language as PolyhedronData["GreatSnubDodecicosidodecahedron"].
Its vertices contain those of the second octahedron 20-compound (E. Weisstein, Aug. 30, 2023).
Its skeleton is the great snub dodecicosidodecahedral graph.
Its circumradius for unit edge length is
Its dual is the great hexagonal hexecontahedron.
