• The symmetry group of the tiling is *2222 (pmm).
• All the internal angles of the constituent polygons are a multiple of 25.71 (π/7)°.
• Contains one regular 14-pointed star polygon with vertex angle of 102.85 (4π/7)°.
• There are 7 non-regular reflective tiles (including 2 kites).
• The tiling satisfies the interlace condition and has one finite interlace and two infinite interlaces with straight cross-overs.
