Tens of thousands of very small PRPs (some under 20 digits) are piling up. FactorDB seems to be proving them, but very slowly (under 1/sec).

Could you please increase the DB number size limit to >75 megabits, or give me a workaround for it? Right now the limit is 62 megabits, and I'm unable to add M74207281 to it, no matter how I express it. That's never happened with any other Mersenne Prime. Eventually, you'll have to remove that size limit altogether, because bigger primes will be found in the future, and I don't want anyone to be prevented from adding the current record prime.

Anyone know how long the DB will be down? It's been saying "Creating backup, offline for ~1 hour" for the past 3 hours.

Finally found a way to add M74207281 to the DB, but I had to add it as M37103641*(2^37103641)1 (2*M74207281) and use "Report Factors" to add the 2 in (WARNING: Takes 26 seconds to come up).

PRP 392^411*11+1 should be easy to prove by N1. But factordb thinks 392^411*11 is 11*19 so N1 is only 0.112% factored.
This probably needs Syd to delete 392^411*11 and add it again. Chris
