Bourgoin, Plate 91

• 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 15°.
• Contains one regular hexagon.
• Contains one regular 8-pointed star polygon with vertex angle of 90°.
• Contains one regular 12-pointed star polygon with vertex angle of 60°.
• There are 6 non-regular reflective tiles (including one kite) and two reflective pairs.
• The tiling satisfies the interlace condition and has no finite interlace and two infinite interlaces with straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 651 polygons.
