COMMENTS

Small Rhombicosidodecahedron: 62 faces, 60 vertices, and 120 edges.

Surface Area = 30+sqrt(30*(10+3*sqrt(5)+sqrt(75+30*sqrt(5)))) = 59.30598284491198954074537543

Circumradius = sqrt(11+4*sqrt(5))/2 = 2.2329505094156900495004153832496827729340807305791816

Midradius = sqrt(10+4*sqrt(5))/2 = 2.1762508994828215111000528659977678801980731915893299472

Quadratic number with denominator 3 and minimal polynomial 9x^2 - 360x - 605. - Charles R Greathouse IV, Apr 25 2016
