• 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 *442 (p4m).
• All the internal angles of the constituent polygons are a multiple of 6°.
• Contains one regular 20-pointed star polygon with vertex angle of 60°.
• There are 12 non-regular reflective tiles (including 3 kites).
• The tiling satisfies the interlace condition and has two finite interlaces and one infinite interlace with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 968 polygons.
