@BillDubuque Technically, we both know that it is not merely 1 bit of information; the proof itself takes up some bits... Anyway, I see that I'm listed as one of the delete-voters; must have mis-clicked earlier... I'm not going to do anything more to this question, and I know your view that questions that are only useful to the asker, but I hope you don't continue deleting good proof-verification questions. Unless you bring it to Meta and the community consensus is that they should be deleted.
