Derived from 4**4 with digons added

• The symmetry group of the tiling is *442 (p4m).
• All the internal angles of the constituent polygons are a multiple of 18°.
• Contains one regular two-pointed star polygon with vertex angle of 36°.
• Contains one regular four-pointed star polygon with vertex angle of 54°.
• The tiling satisfies the interlace condition and has no finite interlace and one infinite interlace with non-straight cross-overs.
• The tiling is edge-to-edge.
• As drawn, contains about 85 polygons.
