It appears the OP deleted the question after receiving an answer: math.stackexchange.com/q/1642111/39599

I think it should be undeleted.

voted to undelete

Another occurence, but this time I was the one that answered: math.stackexchange.com/questions/1642729/…

To be fair, the deletion happened two minutes after I posted my answer, so it may not be deliberate (they may not have seen the new answer).

Not enthusiastic about undeleting the latter one. Easy come, easy go.

The OP's expectation that all inner automorphisms should be involutions is so unrealistic, that counterexamples aren't particularly valuable.

@MichaelAlbanese Undeleted now (and therefore unstarred). I starred your another post, though.

Sure. Just a tiny minor problem that nobody noticed yet. One has to look closely at the title to see it.
