• The symmetry group of the tiling is 632 (p6).
• All the internal angles of the constituent polygons are a multiple of 60°.
• There are no non-regular reflective pairs and one tiles with no mirror image.
• The tiling satisfies the interlace condition and has no finite interlace and one infinite interlace.
• The tiling is edge-to-edge.
• As drawn, contains about 53 polygons.
