We calculate symmetries of the nonlinear n-dimensional wave equation 2nu + m2u − εf(u) n−1∑ ν=0 λν∂u/∂xν = 0 and its approximations. In particular, we study the conformal invariance of the equations. Condi-tional symmetries of the approximate system are also considered whereby approximate solutions are constructed.
