Dye, Figure N 6a

• The symmetry group of the tiling is 22* (pmg).
• All the internal angles of the constituent polygons are a multiple of 90°.
• There are one non-regular reflective pairs and no tiles with no mirror image.
• The tiling satisfies the interlace condition and has no finite interlace and two infinite interlaces with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 53 polygons.
