Pyritohedral symmetry

Pyritohedral symmetry, also known as pyritic symmetry and notated as B3/2, is a 3D spherical symmetry group. It is the symmetry group of the pyritohedral icosahedron and its dual pyritohedron. It is similar to cubic symmetry, but the square axes turn into rectangular axes and the triangular axes turn into chiral triangular ones.
