Snub Icosidodecadodecahedron


U46

The snub icosidodecadodecahedron is the uniform polyhedron with Maeder index 46 (Maeder 1997), Wenninger index 112 (Wenninger 1989), Coxeter index 58 (Coxeter et al. 1954), and Har'El index 51 (Har'El 1993). It has Wythoff symbol |35/35 and faces 12{4/2}+80{3}+12{5}.

The snub icosidodecadodecahedron is implemented in the Wolfram Language as UniformPolyhedron[112], UniformPolyhedron["SnubIcosidodecadodecahedron"], UniformPolyhedron[{"Coxeter", 58}], UniformPolyhedron[{"Kaleido", 51}], UniformPolyhedron[{"Uniform", 46}], or UniformPolyhedron[{"Wenninger", 112}]. It is also implemented in the Wolfram Language as PolyhedronData["SnubIcosidodecadodecahedron"].

It has circumradius for unit edge length of

R=1/2sqrt((2^(4/3)-14x+2^(2/3)x^2)/(2^(4/3)-8x+2^(2/3)x^2))
(1)
=1/2sqrt((2P-1)/(P-1))
(2)
=(64x^6-128x^4+68x^2-11)_2
(3)
=1.12689791279994...,
(4)

where

 x=(25+3sqrt(69))^(1/3)
(5)

and P is the plastic constant.

Its dual polyhedron is the medial hexagonal hexecontahedron.
