The LSND result is shown to fit into a minimal three-flavour neutrino-mixin
g scenario capable of describing all known experimental facts provided the
large Delta M-2 = m(3)(2) - m(2)(2) similar to m(3)(2) - m(1)(2) lies in th
e range 2.5 x 10(-1) < Delta M-2 < 3.0 eV(2). In this range the value of P-
mu tau is expected to be about 5% or larger. (C) 1999 Published by Elsevier
