• The symmetry group of the tiling is *442 (p4m).
• All the internal angles of the constituent polygons are a multiple of 7.5°.
• Contains one square.
• Contains one regular octagon.
• Contains one regular 6-pointed star polygon with vertex angle of 60°.
• Contains one regular 8-pointed star polygon with vertex angle of 90°.
• There are five non-regular reflective tiles (including one kite).
• The tiling satisfies the interlace condition and has two finite interlaces and no infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 269 polygons.
