• The symmetry group of the tiling is 2*22 (cmm).
• All the internal angles of the constituent polygons are a multiple of 9°.
• Contains two regular 8-pointed star polygons with vertex angle of 90°.
• Contains one regular 10-pointed star polygon with vertex angle of 72°.
• There are 8 non-regular reflective tiles (including 2 kites) and three reflective pairs.
• The tiling satisfies the interlace condition and has one finite interlace and no infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 563 polygons.
