• The symmetry group of the tiling is 442 (p4).
• All the internal angles of the constituent polygons are a multiple of 45°.
• Contains two regular 8-pointed star polygons with vertex angle of 90°.
• There is one non-regular reflective tile and one tile with no mirror image.
• The tiling satisfies the interlace condition and has no finite interlace and one infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 120 polygons.
