Bourgoin, Plate 21

• 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 *632 (p6m).
• All the internal angles of the constituent polygons are a multiple of 30°.
• Contains one regular two-pointed star polygon with vertex angle of 60°.
• Contains one regular hexagon.
• Contains one regular 6-pointed star polygon with vertex angle of 60°.
• There are five non-regular reflective tiles (including one kite).
• 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 545 polygons.
