Hexagon has no degrees of freedom but can seen as directed edges. Hexagons of symmetry g2, i4, and r12, as parallelogons can tessellate the Euclidean plane by translation. Other hexagon shapes can tile the plane with different orientations. The 6 roots of the simple Lie group , represented by a Dynkin diagram , are in a regular hexagonal pattern. The two simple roots have a 120° angle between them. The 12 roots of the Exceptional Lie group G2, represented by a Dynkin diagram are also in a hexagonal pattern. The two simple roots of two lengths have a 150° angle between
A Road at Saint-Remy with Female Figure winds. There is some contrast between the windy yellow and green vegetation which dominates the female figure, and the blue open sky overhead. A Road at Saint-Remy with Female Figure Vincent van Gogh painted A Road at Saint-Remy with Female Figure while staying in Saint-Remy in 1889.
