• The symmetry group of the tiling is *442 (p4m).
• All the internal angles of the constituent polygons are a multiple of 45°.
• Contains two regular two-pointed star polygons with vertex angle of 45°.
• Contains 7 regular 8-pointed star polygons with vertex angle of 90°.
• There are 12 non-regular reflective tiles (including one kite and one dart) and one reflective pair.
• The tiling satisfies the interlace condition and has 6 finite interlaces and one infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 1209 polygons.
