The ground-state cohesive energy per electron of the composite fermion (CF) Fermi sea, the Laughlin state, and the charge density wave (CDW) at higher Landau levels (LL's) are computed. It is shown that whereas for n>~2 LL, the CDW state is generally more energetically preferable than those of the CF liquid and the Laughlin liquid, the \ensuremathν=4+1/6 CF liquid state unexpectedly has lower ground-state energy than that of the CDW state. We suggest this CF liquid between the Wigner crystal and the bubble phase may lead to the crossover from the normal integer quantum Hall liquid to the re-entrant integer quantum Hall state observed in the recent magnetotransport experiments.
