Chiral dodecahedral symmetry

H3+, also known as kidoic symmetry, chiral dodecahedral symmetry, or chiral icosahedral symmetry, is a 3D spherical Coxeter group. It is the symmetry group of the snub dodecahedron, or equivalently the symmetry group of the dodecahedron and icosahedron with all the reflections removed.
