  If the upper limit on the effective (Majorana) neutrino mass from
neutrinoless double beta decay experiments is confirmed to be much less than an
electron-volt, then one way to reconcile it with the degenerate neutrino mass
pattern suggested recently to explain the observed deficit of solar and
atmospheric neutrinos as well as neutrinos as HDM is to postulate that there be
maximal mixing among the three light (or two) neutrinos. This suggestion is
advanced in this paper and is analysed.
