34. A rhombus-shaped vortex state is not consistent with the C4 -symmetry and it does not appear as a metastable state in a perfect square for L=4. However, the presence of imperfections (or other vortices as, e.g., outer-shell vortices for states with L=12 and 16) favors appearance of triangular- or rhombus-shaped vortex configurations.
