• The symmetry group of the tiling is 632 (p6).
• All the internal angles of the constituent polygons are a multiple of 60°.
• Contains one equilateral triangle.
• Contains one regular two-pointed star polygon with vertex angle of 60°.
• Contains one regular 6-pointed star polygon with vertex angle of 60°.
• There are no non-regular reflective pairs and one tile with no mirror image.
• The tiling does not satisfy the two-colour condition.
• The tiling is not edge-to-edge.
• As drawn, contains about 151 polygons.
