In geometry of the Euclidean plane, a 33344-33434 tiling is one of two of 20 2-uniform tilings of the Euclidean plane by regular polygons. They contains regular triangle and square faces, arranged in two vertex configuration: 3.3.3.4.4 and 3.3.4.3.4. The first has triangles in groups of 3 and square in groups of 1 and 2. It has 4 types of faces and 5 types of edges. The second has triangles in groups of 4, and squares in groups of 2. It has 3 types of face and 6 types of edges.
