We find all possible relations among physical observables arising fromneutrino mass matrices that describe in a natural way the currently observedpattern (tan_23 and tan_12 large, dm^2_Sun/dm^2_Atm and tan_13 small) in termsof a minimum number of parameters. Natural here means due only to the relativesmallness (vanishing) of some parameters in the relevant lagrangian, withoutspecial relations or accidental cancellations among them.Comment: 14 pages, 1 eps figur
