• Growth dynamic build of this pattern.
• Random dynamic build of this pattern.
• Structured dynamic build of this pattern.
• The symmetry group of the tiling is *X (cm).
• All the internal angles of the constituent polygons are a multiple of 36°.
• Contains five regular two-pointed star polygons with vertex angle of 72°.
• Contains 11 regular pentagons.
• There are 7 non-regular reflective tiles (including one kite).
• The tiling satisfies the interlace condition and has one finite interlace and two infinite interlaces with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 462 polygons.
