Subgroup-conjugating not implies class-preserving
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., subgroup-conjugating automorphism) need not satisfy the second automorphism property (i.e., class-preserving automorphism)

A subgroup-conjugating automorphism of a group (i.e., an automorphism that sends every subgroup to a conjugate subgroup) need not be class-preserving: it need not send every element to a conjugate element.
- Universal power not implies class-preserving
- Universal power not implies IA
- Universal power not implies center-fixing
- Subgroup-conjugating not implies IA
- Subgroup-conjugating not implies center-fixing
The proof follows directly from combining facts (1) and (2).
