RESUMEN

            The infinitely many commuting symmetries and recursion operator of a recently introduced KdV-type equation, μ_t + βt²ⁿ⁺¹(μ_XXX -6μμ_X) + (n+1/t)(xμ_X + 2μ) = 0 is studied in this letter. it is found that this new equation has two types of symmetries which are generated by the same recursion operator. The Lie algebra hat associated to the two types of symmetries is also found.
