Dye, Figure R 6a

• The symmetry group of the tiling is 442 (p4).
• All the internal angles of the constituent polygons are a multiple of 45°.
• There are no non-regular reflective pairs and one tile 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 40 polygons.
