Is there a way to use bot to post many numbers in a sequence to factordb?
In thread https://mersenneforum.org/showthread.php?t=16445, there is a way to use bot to post many numbers for Aliquot sequence (also home primes sequence) in factordb, however, is there a way to use bot to post Bell(n), Euler(n), Pell(n), Tribonacci(n), Perrin(n), Padovan(n), Fubini(n), Motzkin(n), Wolstenholme(n), A(n), K(n), Partition(n), DistinctPartition(n), Sm(n), SmWl(n), and A000521(n) in factordb, for all 1<=n<=10000? Also for the first n digits for many mathematical constants (pi, e, gamma, sqrt(2), ln(2), golden ratio, ...) for all 1<=n<=10000?

You should only add them as you factor them. In other words, don't add a number unless you want to factor it, or you want someone else to factor it, if there's anyone willing to do so. Numbers <10^69 are automatically sent to the DB workers to factor.
Also, I think the first 900 or so numbers of the form floor(pi*10^n) are already on the DB. Last fiddled with by Stargate38 on 20210610 at 17:32

There is already a project to factor the Euler zigzag numbers (this project includes the evenindex Euler zigzag numbers and the numerator of the Bernoulli numbers, and factor the oddindex Euler zigzag numbers is equivalent to factor 2^(n+1)1 (this is a Cunningham number) and factor the Bernoulli number B(n+1)) However, there seems to be no project to factor the Bell numbers, the Fubini numbers, the Pell numbers, the Tribonacci numbers, ... (at most to find large primes in these sequences) (this site is to factor (p^p1)/(p1) and (p^p+1)/(p+1) for prime p, i.e. the Pisano period of the Bell numbers mod p for prime p, not to factor the Bell numbers) There is also a project to factor the partition numbers, and find large primes (e.g. 40000digit partition(1289844341)), but not for the distinct partition numbers Last fiddled with by sweety439 on 20210610 at 19:39

now we know who was polluting the DB all this time!
and we blamed the poor cmd for it!

Actually, cmd put a bunch of numbers on there, too. I've found quite a few from those years. Also, some of the users that have been banned indefinitely might be taking revenge as well (i.e. Samuel), but that's just speculation. It could be that there are so many people accessing the DB simultaneously that it just looks like flooding.
