NEVER MIND --- the same moderator who suggested I post here has solved the problem by deleting my copy-paste job and undeleting the answer we wanted undeleted. [or maybe it got undeleted by some other mechanism]
This concerns Can a positive binary quadratic form represent 14 consecutive numbers?
Some years ago, an answer was posted. It received 14 upvotes, and no downvotes. A couple of years later, that answer was deleted by its author. I used copy-paste to put up a "new" answer, whose content was just that of the old answer, and I made it community wiki.
It has been suggested that it would have been better to go to meta to request undeletion of the old answer --- only those with 20K+ can vote to undelete. So, here I am.
If/when the old answer is undeleted, I'll delete my copy-paste job.
