In this paper, we consider a hyperbolic generalized Fisher-KPP equation: "2utt +g(u)ut = (k(u)ux)x +f(u) where f,
g and k are arbitrary smooth functions of variable u and " is a speed parameter. We nd invariant solutions by Lie
method. Also, we study standard and weak conditional and approximate symmetries.<
