Abstract：In this paper , the discrete Lie point symmetry group analysis method is applied on the ( 1+1 ) dimensional nonlinear differential -difference Toda-like equation, i.e.firstly, the conditional symmetries is in-troduced, after that the overdetermined equations are solved , and then similarity reduction for the equation is done , and the new exact solutions of this equation are obtained .
