• The symmetry group of the tiling is *2222 (pmm).
• All the internal angles of the constituent polygons are a multiple of 30°.
• Contains two regular two-pointed star polygons with vertex angle of 60°.
• There is one non-regular reflective tile (including one dart).
• The tiling satisfies the interlace condition and has no finite interlace and two infinite interlaces with non-straight cross-overs.
