• We work with a finite relational vocabulary with at least one relation symbol with arity at least 2. Fix any integer m > 1. For almost all finite structures (labelled or unlabelled) such that at least m elements are moved by some automorphisms, the automorphism group is ( Z 2 ) i for some i ≤ ( m + 1 ) / 2 ; and if some relation symbol has arity at least 3, then the automorphism group is almost always Z 2 .
