• The symmetry group of the tiling is 2*22 (cmm).
• All the internal angles of the constituent polygons are a multiple of 36°.
• Contains 48 regular two-pointed star polygons with vertex angle of 72°.
• Contains 20 regular pentagons.
• Contains one regular 10-pointed star polygon with vertex angle of 72°.
• There are 8 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 1155 polygons.
