It seems that the db is filled with approximatelly 5000+ low integer that are less than 5 digits and are all in the form of

Anyway, maybe someone can email Syd to get these fixed.

Wow, this backend needs a better algebra system.

Overnight some nitwit added 8 C89's and 1 C90 of the form 2^572%2^286*286 that the database does not parse correctly as noted earlier in this thread.

Does anyone know if Syd is still reading this thread? In the factor tables there's the wrong entry for Proth numbers (called Cullen there) and the Sylvester/Euclid sequence could be fixed so it won't terminate at primes.
On the other hand, is there a specific reason that that sequence is in the db and won't add new terms until the last one is factored? It doesn't require factorization to calculate the next term.

I don't think he is routinely keeping up with the forum threads. In the past, when I've contacted him, I used the email at the bottom of the "imprint" page. He's always been quite responsive to db issues, when contacted.

I've noticed that the DB has been running slow. Is someone flooding it, or is there a hardware issue?

I don't know if this is the same issue that you were having, but the DB is being flooded. Someone is adding millions of 4xdigit numbers, many of the form 10^46+n, along with their factorizations, and there is now a backlog of millions of unproved small PRPs which is preventing other PRPs from being proved. I've dropped Markus an email. If the user responsible happens to be reading this forum, please could you stop?
