This question How do you prove that $n^2-1$ is composite when $n>2$? was closed as a duplicate. That was the right outcome, as opposed to, you know, "off-topic."
But the question it's a duplicate of is closed! Prove that there doesn't exist any integer $x \ge 3$ such that $x^2-1$ is prime. At le...
Maybe it could be useful to have also a query which omits those ones where the duplicate target is closed as a duplicate. (And only leave other close reasons.)
I am not really sure how to do that. Should I use PostLinks JOIN PostHistory and check for CloseReasonId? I'm guessing that this would be rather slow, since PostHistory table is probably bigger than Posts.
Should questions ever be marked a duplicate of another duplicate question?
Specifically, I'm looking at these three questions, each one marked as a duplicate of the next:
?+?+?=30 (1,3,5,7,9,11,13,15)
What three odd integers have a sum of 30?
What five odd integers have a sum of 30?
