* An Approach to Permutation Symmetry for Neutrinos*

Abstract 

Recent experimental data suggest that the leptonic mixing matrix, one of 
the chief unsolved problems in elementary particle physics, is very 
close to the so-called "tribimaximal form". Such a structure is natural 
in the context of permutation symmetry. Inspired by this we implement 
the S_3 group as a zeroth order approximation into the electroweak 
theory and S_2 subgroups of it as first order and second order 
perturbations.
