• The symmetry group of the tiling is 2*22 (cmm).
• All the internal angles of the constituent polygons are a multiple of 36°.
• Contains five regular five-pointed star polygons with vertex angle of 36°.
• Contains two regular 10-pointed star polygons with vertex angle of 72°.
• There are five non-regular reflective tiles (including one kite).
• The tiling satisfies the interlace condition and has no finite interlace and four infinite interlaces with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 574 polygons.
