[QUOTE=wblipp;321312]How do you tell this?[/QUOTE]

If a number is FF (and belongs to a sequence), then the More information arrow will show an aliquot sequence association. Like this recent number from sequence [URL="http://factordb.com/index.php?id=1100000000559800787"]4788[/URL].

P.S. Then click the green arrow after "More information."

[QUOTE=firejuggler;321314]a few minutes ago there was 72 000 P95 , now it is at 112 000 prime of 95 digits long[/QUOTE]

Grrr! the prp95 digit bandit is at it again.....

There are no more unknown numbers below <19400 digits - maybe it can expand to 19500 digits? :)

Use [url=http://www.factordb.com/listtype.php?t=2&mindig=1&perpage=100&start=0]this[/url] instead.

I downloaded the Primo input file for [URL="http://www.factordb.com/index.php?id=1100000000379369160"]this 2489-digit PRP[/URL]. Both Primo and another program confirm the number is composite, with Primo reporting "The candidate is not a Lucas strong pseudoprime for (P=1, Q=3)."

Is there a way to kick factordb into running another primality test? I presume this isn't exceptionally rare, since the Status Page reports some 19000+ "probable primes that failed primality proof or had a factor". Thanks!

It is composite by a simple N+1 test. It is also trivially composite in base 7 or 11.
There are plenty of PRPs by one-sided tests in a single base.

I guess it is indeed a question to Markus.

In fact, it has a factor 2855137952289193586798729541499

I'm having a problem. Why is the Status page not loading past the "Distribution of numbers by type" graph?

factordb.com homepage is broken

Same here, the status page is broken, can't access the composite-numbers-without-factors list and can't access to found factors and submitted certificates :no:

In the last couple of days a large number of small composites has been dumped into the database (not by me). I spent some time trying to clear most of them, but for some reason there are a few C19 that the workers don't seem to be clearing.

I'm also working on these small composites.
