• The symmetry group of the tiling is 4*2 (p4g).
• All the internal angles of the constituent polygons are a multiple of 45°.
• There is one non-regular reflective tile.
• The tiling satisfies the interlace condition and has no finite interlace and one infinite interlace.
• The tiling is edge-to-edge.
• As drawn, contains about 63 polygons.
