Add to ORKGWe give a series of interesting subgroups of finite index in Aut(Fn). One of them has index 42 in Aut(F3) and infinite abelianization. This implies that Aut(F3) does not have Kazhdan's property (T) (see [3] and [6] for another proofs). We proved also that every subgroup of finite index in Aut(Fn), n >= 3, which contains the subgroup of IA-automorphisms, has a finite abelianization
