16. In general, the symmetry of the lowest energy level of FCEL does not directly indicate the symmetry properties of the ground state of the original Hamiltonian. However as checked later in the calculations of the magnetization, the symmetry of the lowest level in the odd L step seems to reflect the ground state properties in the present case.
