6 or 4?
The type of symmetry of this park in Sydney (Australia) changes according to what we decide to consider: the fountain in the centre has the shape of a regular hexagon and so it has symmetry D6. The symmetry breaks into a D3 if we consider the internal part of the fountain. If we look over the circle, the roads that arrive at the fountain have a dihedral symmetry of type D4.
