• The symmetry group of the tiling is *2222 (pmm).
• All the internal angles of the constituent polygons are a multiple of 36°.
• Contains 12 regular five-pointed star polygons with vertex angle of 36°.
• Contains two regular 10-pointed star polygons with vertex angle of 72°.
• There are four non-regular reflective tiles (including one kite).
• The tiling satisfies the two-colour condition with straight cross-overs, but interlace counts not determined.
• The tiling is edge-to-edge.
• As drawn, contains about 771 polygons.
