Group analysis of generalized fifth-order Korteweg-de Vries equations   with time-dependent coefficients
  We perform enhanced Lie symmetry analysis of generalized fifth-order Korteweg-de Vries equations with time-dependent coefficients. The corresponding similarity reductions are classified and some exact solutions are constructed.
