I wanted something done, so I have sent Markus an email regarding the modulo operator issue.

@Sweety439: For the n-th prime, you could use Pari/gp's prime(n) function, and then paste the output to the DB. The amount of time depends on n.

However, factordb has "product of the first n primes" (n##), but does not have "n-th prime", I really think that it is not reasonable (of course, you can type "n##/(n-1)##" for the n-th prime, but n## may exceed the factordb limit (see this example))

I heard back from him about a week ago. He said the issue was with the term optimizer not setting the brackets properly on some formulas with the modulo operator, thus leading to a hash mismatch and factors not being accepted. He's working on a fix.

(Sweety: please don't spam him with lots of stupid suggestions. That might make him less willing to pay attention to serious suggestions.)
I'd love to drop Markus an email with a few suggestions I have for improving things in FactorDB. However, I do not have his email address, which makes things a bit difficult. Can someone oblige, please.

http://www.factordb.com/datenschutz.html - scroll to the end. I assume it is current.

I am doubt that it is really current, since I have emailed him with this address, but he did not reply.

Does factordb run Baillieโ€“PSW primality test for the PRPs? And does factordb do the trial division for the PRPs (and if so, what is the limit of trial division?)?

Also, the "Check base (2-255)" box for probable primes are Miller-Rabin tests? Or just Fermat tests?

It is his current address. He probably didn't reply to you because your suggestions were unnecessary and/or stupid.

It the address were not current, your email would have bounced.

Unless your From: header was itself an invalid address.

A technique quite often used by spammers.
