• The symmetry group of the tiling is 2222 (p2).
• All the internal angles of the constituent polygons are a multiple of 90°.
• Contains four squares.
• There is one non-regular reflective tile.
• 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 95 polygons.
