A stability analysis of the hexagonal structures is performed numerically. Depending on the wavenumber of the hexagons different instabilities are predicted. Some of them take place at a finite wavenumber and result in the formation of structures with twelve spatial modes. These structures are compared with those observed experimentally.The authors acknowledge financial support from the European Science Foundation (PHASE network).
