  The LSND result is shown to fit into a minimal three-flavour neutrino-mixing
scenario capable of describing all known experimental facts provided the large
Delta M^2 = m_3^2 - m_2^2 \sim m_3^2 - m_1^2 lies in the 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.
