Abstract: | LetF be a free group andR≤F a characteristic subgroup. Automorphisms ofF/R which are induced by automorphisms ofF are called tame. In this paper we use theN-torsion invariant discovered by the first author and M. Lustig LM] to show the existence of non-tame automorphisms of free
central extensions and free nilpotent extensions of Burnside groups.
