What is the least degree that a hexagon has of point of symmetry?

A regular hexagon has six lines of symmetry, each passing through a vertex and the midpoint of the opposite side, or through the midpoints of opposite sides. Therefore, the least degree of symmetry for a hexagon is 60 degrees, as the hexagon can be rotated by this amount and still look the same. However, if considering any hexagon (not just regular), the point of symmetry can vary widely.
