Is the C93 from line 99 booked, or not? Just curious. I ECMed it to t31 (no factors), but I didn't want to run SIQS on it if someone else had it reserved.

EDIT: I went ahead and did it, since it...

I use those "Greatest Prime Factor" sequences (mostly GPF^3+1 and GPF^3-1, but I've also run the q^2-1 sequences of all factored RSA numbers) to see if they ever end in a cycle, so we can't get rid...

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...

Can someone please post the full list of numbers, along with reservations? I would like to try one of the smaller ones (SNFS difficulty <140), if there are any unreserved.

Maybe a later term will be the cycle's start. We don't know if that'll happen yet, but the later terms aren't untouchable. Other sequences (i.e. 10000018198 and 31657014970784) merge with 276.

Maybe it should be that such status updates can only be posted to numbers that already exist in the DB, and are of a special form (i.e. a*b^c+/-d), or are a factor of such a number ((a*b^c+/-d)/e).

If interpreted as either Base-25 or Base-30, it's prime:

The highest known termination is that of 2^82589933 (and by extension (M82589933)^2), and will always be a power of 2 sequence, as 2^n becomes Mn after 1 term. However, that's trivial. Since you're...
