Lee tiling, Figure 21

• The symmetry group of the tiling is 2*22 (cmm).
• All the internal angles of the constituent polygons are a multiple of 18°.
• There are two non-regular reflective tiles and one reflective pair.
• The tiling satisfies the two-colour condition.
• The tiling is edge-to-edge.
• As drawn, contains about 190 polygons.
