On the automorphism groups of the free metabelian Lie algebras

Let $M_n$ be a free metabelian Lie algebra of a finite rank $n > 3.$ It is proved that the automorphism group $AutM_n$ is generated by the set of all elementary and inner automorphisms of $M_n.$ In contrast, it is proved that the automorphism group $AutM_3$ is not generated by such set. Moreover, $AutM_3$ contains non-tame primitive elements.
