We consider the variable coe cient inhomogeneous nonlinear di usion equations of the form f(x)ut =[g(x)u n ux] x . We present a complete classiΓΏcation of Lie symmetries and form-preserving point transformations in the case where f(x) = 1 which is equivalent to the original equation. We also introduc
