Bourgoin, Plate 165

• The symmetry group of the tiling is 2*22 (cmm).
• All the internal angles of the constituent polygons are a multiple of 25.71 (π/7)°.
• Contains one regular 14-pointed star polygon with vertex angle of 51.42 (2π/7)°.
• There are 8 non-regular reflective tiles (including 2 kites).
• 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 545 polygons.
