• All the internal angles of the constituent polygons are a multiple of 7.5°.
• Contains three regular 8-pointed star polygons with vertex angle of 90°.
• Contains two regular 8-pointed star polygons with vertex angle of 45°.
• Contains one regular 12-pointed star polygon with vertex angle of 60°.
• There are 14 non-regular reflective tiles (including 2 kites and one dart) and two reflective pairs.
