Prime Curios! 47, hosted by Chris Caldwell, a mathematics professor at the University of Tennessee at Martin known for his long running Prime Pages project, correctly classifies 47 as a safe prime, a real and checkable mathematical property. Its strength is that it is maintained by a working number theorist. Its limit is that the wider Prime Curios! entries mix rigorous mathematics with numerological and cultural trivia submitted by readers; this atlas cites it for the checkable mathematical classification, not for any numerological claim the same page may also carry.

Assessment
Reliability Tier2
Prime Curios! 47, hosted by Chris Caldwell, a working number theorist at the University of Tennessee at Martin, the middle tier reflecting a specialist's maintained reference page rather than a peer reviewed publication, weighed against its checkable mathematical accuracy for 47's classification as a safe prime. Cited for that mathematical fact alone, never for the same page's numerological or cultural trivia. NotesMaintained mathematical-curiosities reference, consulted for 47's classification as a safe prime.
