The photo shows a band round the repeat area which is not included in this representation.

• The symmetry group of the tiling is 4*2 (p4g).
• All the internal angles of the constituent polygons are a multiple of 45°.
• Contains two squares.
• Contains 12 regular 8-pointed star polygons with vertex angle of 90°.
• There are 9 non-regular reflective tiles (including one kite and one dart) and one reflective pair.
• The tiling satisfies the two-colour condition with straight cross-overs, but interlace counts not determined.
• The tiling is edge-to-edge.
• As drawn, contains about 2105 polygons.
