Image with dihedral symmetry formed by a polar spin of an attractor with p3 symmetry. This construction is described as p3-enhanced C_6 symmetry in the paper: Nathan C. Carter, Stephen M. Grimes, and Clifford A. Reiter, Frieze and Wallpaper Chaotic Attractors with a Polar Spin, Computers & Graphics, to appear. Many similar illustrations of planar enhanced cyclic symmetry are given there.
