I answered a question earlier today. It asked something like for an element $g$ of a free group, does there exist a finite-index subgroup of the free group such that g is a basis element of the subgroup. The author seems to have deleted the question. I can't seem to find it in my history (but I switch computers frequently and don't remember which one I was using).

Can a moderator locate the deleted question? One concern of mine is that it would have been a pretty good homework question for an course in geometric group theory. That's the only real reason I can imagine it being deleted (since it had multiple upvotes when I answered it).

`deleted:1`

, so if it was your answer that is a good way to find it (this is a 10k rep thing, though). Also, in your profile there is a link on the Answers tab of recently deleted answers. $\endgroup$ – Asaf Karagila♦ Oct 15 '16 at 5:56
