A rosette
At first sight, this rosette seems to have a dihedral symmetry of type D36. Indeed, if we observe more closely, we realize that the symmetry axes relative to the external circular annulus don't coincide with those of the internal annulus. The whole drawing has no symmetry axes, but there are some rotations (of multiples of 10°) that send the figure in itself. So, the rosette has cyclic symmetry of type C36. This image shows a different colouring of the drawing.
