The small dodecicosahedron is the uniform polyhedron with Maeder index 50 (Maeder 1997), Wenninger index 90 (Wenninger 1989), Coxeter index 64 (Coxeter et al. 1954), and Har'El index 55 (Har'El 1993). It has Wythoff symbol and its faces are .
The small dodecicosahedron is implemented in the Wolfram Language as UniformPolyhedron[90], UniformPolyhedron["SmallDodecicosahedron"], UniformPolyhedron["Coxeter", 64], UniformPolyhedron["Kaleido", 55], UniformPolyhedron["Uniform", 50], or UniformPolyhedron["Wenninger", 90]. It is also implemented in the Wolfram Language as PolyhedronData["SmallDodecicosahedron"].
Its skeleton is the dodecicosahedral graph, illustrated above in a few embeddings.
Its circumradius for unit edge lengths is
Its dual polyhedron is the small dodecicosacron.
