The threefold maximal mixing scenario [60, 61] assumes a
democratic (i.e. 1/3, 1/3, 1/3) flavour content for the neutrino
mass eigenstates. The "large" 
is basically constrained
by the atmospheric neutrino data in the range relevant for LBL
experiments. The "small" is weakly constrained by
solar neutrino data to be below 
. The Homestake and
Kamiokande data cannot be fit simultaneously in this scenario [62].
The LSND results (and, in general, any evidence of
oscillations with in the 
range) cannot be
accommodated in this framework, which is anyway compatible with
the other negative searches at accelerators and reactors [60, 62].
