• The symmetry group of the tiling is *632 (p6m).
• All the internal angles of the constituent polygons are a multiple of 30°.
• Contains two equilateral triangles.
• Contains one regular four-pointed star polygon with vertex angle of 60°.
• Contains one regular 12-pointed star polygon with vertex angle of 90°.
• There are three non-regular reflective tiles (including one kite).
