I wanted to search for ♯ http://meta.math.stackexchange.com/questions/12334/are-these-two-questions-on-gcd-of-powers-of-a-and-b-duplicates and
♯ http://meta.math.stackexchange.com/questions/12330/any-question-or-answer-on-the-main-site-about-this-lemma. I tried
but nothing is here. Additionally I tried http://meta.math.stackexchange.com/a/13302/85100.
All in all, after multifold comments and searches by Martin Sleziak kindly, only moderator Alex Becker found them. By reason of time and effort, I thence request that all users can access and see their own deleted answers and questions.
