The list of composites with no known factors, http://factordb.com/listtype.php?t=3 has problems at 71 and 75 digits. wget gets:

N1 Proof test has been delayed for several days (maybe it's a system error?):
http://www.factordb.com/index.php?id...00001362414421 "This number is already in queue for N1test." The large N1 factor can be found here. Thanks to who knows what's going on. BTW, How long would it take to prove a random 20,000 digit prime using N1? I plan to enter one in the database soon I hope it won't stress out the system any more.

I'm looking for easy N1 proofs these days, and i noticed this too. Maybe is giving priority in checking Primo certificates, if N1 has a lot factors? Usually i see dozens of certificates in queue. (it's just a guess, i actually don't know how the db handles its queues).

A 1344dd number that I certified Saturday has been stuck verifying for around 48 hours at this point.

(4386^689+2067^1462)/3^689/2705 (4515 digits) submitted by Masaki UKAI is also stuck.
And the load average earlier today was less than 1 so it doesn't look as if they are being processed. Chris

This ID is for the expression (10^79181)%(10^791)/9. Can you explain why such an expression was generated? 10^79181 is less than 10^791, so the % operator doesn't actually do anything here. It's the same number as just (10^79181)/9. Of course, if you query that expression, it shows up as prime.

I have no idea. it was the 'smallest composite without a factor' at the time.
