• The symmetry group of the tiling is *442 (p4m).
• All the internal angles of the constituent polygons are a multiple of 15°.
• Contains two regular 12-pointed star polygons with vertex angle of 60°.
• There are five non-regular reflective tiles (including one kite).
• The tiling satisfies the interlace condition and has one finite interlace and one infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 247 polygons.
