The great truncated icosahedron, also called the truncated great icosahedron, is the uniform polyhedron with Maeder index 55 (Maeder 1997), Wenninger index 95 (Wenninger 1989), Coxeter index 71 (Coxeter et al. 1954), and Har'El index 60 (Har'El 1993). It has Schläfli symbol and Wythoff symbol . Its faces are .
The great truncated icosahedron is implemented in the Wolfram Language as UniformPolyhedron[95], UniformPolyhedron["GreatTruncatedIcosahedron"], UniformPolyhedron["Coxeter", 71], UniformPolyhedron["Kaleido", 60], UniformPolyhedron["Uniform", 55], or UniformPolyhedron["Wenninger", 95]. It is also implemented in the Wolfram Language as PolyhedronData["GreatTruncatedIcosahedron"].
Its circumradius for unit edge length is
Its dual is the great stellapentakis dodecahedron.
