  The electronic free energies in metal clusters are calculated based on a
simple ladder spectrum for the level degeneracies three and four, and compared
with the known results for degeneracies one and two. The low temperature and
the asymptotic high temperature results for free energy differences are
generalized to ladder spectra of any degeneracy. Remarkably, free energy
differences do not approach zero at high energies for size-independent Fermi
energies.
