(3.3.4^**_π/6;3.4^*_π/6.4^**_π/6.4^*_π/6)

• The symmetry group of the tiling is 2*22 (cmm).
• All the internal angles of the constituent polygons are a multiple of 30°.
• Contains one equilateral triangle.
• Contains one regular four-pointed star polygon with vertex angle of 30°.
• The tiling does not satisfy the two-colour condition.
• The tiling is edge-to-edge.
• As drawn, contains about 136 polygons.
