Bourgoin, Plate 125

• The symmetry group of the tiling is *632 (p6m).
• All the internal angles of the constituent polygons are a multiple of 1°.
• Contains three regular pentagons.
• Contains one regular 9-pointed star polygon with vertex angle of 72°.
• Contains one regular 12-pointed star polygon with vertex angle of 72°.
• There are 13 non-regular reflective tiles and one reflective pair.
• 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 493 polygons.
