Aiming for unification of Lμ - Lτ and the standard model gauge group

In this letter we show a kind of L-mu - L-tau gauge symmetry can be unified into a simple group E-7 with the standard model gauge symmetry in the context of coset space unification. We also discuss some implication from one of this kind of unification.
