Normal not implies subgroup-conjugating
This article gives the statement and possibly, proof, of a non-implication relation between two automorphism properties. That is, it states that every automorphism satisfying the first automorphism property (i.e., normal automorphism) need not satisfy the second automorphism property (i.e., subgroup-conjugating automorphism)

- Class-preserving not implies subgroup-conjugating: An automorphism of a group that preserves conjugacy classes of elements need not send every subgroup to a conjugate subgroup.
The proof follows directly by piecing together facts (1) and (2).
