Derived from 3.3.3.4.4, with digons added, angle 45 degrees;

• The symmetry group of the tiling is 22X (pgg).
• All the internal angles of the constituent polygons are a multiple of 15°.
• Contains four regular two-pointed star polygons with vertex angle of 45°.
• Contains two regular three-pointed star polygons with vertex angle of 15°.
• Contains one regular octagon.
• Contains one regular four-pointed star polygon with vertex angle of 45°.
• The tiling satisfies the two-colour condition.
• The tiling is edge-to-edge.
• As drawn, contains about 95 polygons.
