Bourgoin, Plate 78

• 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 three-pointed star polygon with vertex angle of 105°.
• Contains one regular 12-pointed star polygon with vertex angle of 75°.
• There are four non-regular reflective tiles.
• The tiling satisfies the interlace condition and has no finite interlace and two infinite interlaces.
• The tiling is edge-to-edge.
• As drawn, contains about 399 polygons.
