Dye, Figure O 4b

• The symmetry group of the tiling is 2*22 (cmm).
• All the internal angles of the constituent polygons are a multiple of 45°.
• There is one non-regular reflective tile and one reflective pair.
• The tiling satisfies the interlace condition and has no finite interlace and three infinite interlaces with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 62 polygons.
