Bourgoin, Plate 168

• The symmetry group of the tiling is 2*22 (cmm).
• Contains one regular two-pointed star polygon with vertex angle of 77.1 (3π/7)°.
• Contains one regular 7-pointed star polygon with vertex angle of 77.1 (3π/7)°.
• Contains one regular 14-pointed star polygon with vertex angle of 70.7 (11π/28)°.
• There are 15 non-regular reflective tiles and two reflective pairs.
• The tiling satisfies the interlace condition and has 6 finite interlaces and no infinite interlace.
• The tiling is edge-to-edge.
• As drawn, contains about 553 polygons.
