Complex polyhedra (C3)[edit]

There are 9 unique regular and uniform complex polyhedra from 14 Wythoff constructions (ringed patterns) in the L3 and M3 Shephard groups. These polyhedra can be seen a complex analogues of tetrahedral symmetry and octahedral symmetry of the regular tetrahedron, cube, and octahedron.
