Looks like someone is already running this sequence. I guess reservations may be optional here.

Not necessarily.....if a sequence is not reserved in this thread and the remaining composite on a line is under 108 digits or so either bchaffin's aliquot workers or the distributed DB workers are liable to factor the composite and extend a sequence.

bchaffin's workers will not factor composites from sequences reserved here, but the other DB workers might, if they're small enough. (And looking at the top post, no one had edited it to reflect your latest reservation; I remedied that, so feel free to either continue with this one or pick another one.)

If you want something that might be a little more interesting than the ones you've been running, let me know and I can look for something that might have a little more potential.....

I'm just trying to understand the rules here. A note on the reservation list stating the above would have steered me away from anything < 108 digits.

I'll let that one go because it's potential has already been used up.

I'm just did an experiment by querying the DB with a number up around 135e9 and something went and calculated the first 700 or so lines. I'm assuming it was the db workers. Kinda takes the fun out of everything.

Noted. We don't get many newbies around here, so everything's kind of geared toward people who have been doing this a while. If you have any questions beyond the basics, just ask and someone here will help out.

<checks DB> Unfortunately, you're right; there was a nice downdriver run in there. The nice thing now, though, is that the workers can work on the sequence and it might manage an escape from the driver.

Well, it depends on what you defiine as taking the fun out....I've been doing aliquot sequence factoring since '07 and haven't thought about quitting yet.

Releasing 955296 at i7776, size 149, 2^2 * 7 * c148.

It had a remarkable run of over 5000 terms in the 10-60 digit range, but then it just went up and up. After a promising time without a driver (during which it decreased from 151 digits to 148) it picked up 2^2 * 7. Oh well...

May I reserve 890960 and (probably very briefly) 281592?

398856 is currently at iteration 1152 with 2^4

[fivemack]

Abandoning 741450 (iteration 1473, 2^6 * 127 * C130). 7000@1e6 so probably ready for GNFS.

[fivemack]

Abandoning 754320 (iteration 1172, 2^2 * 7^2 * C132); 7000@1e6 done on the C132

[fivemack]

Reserve 309180 (iteration 404, 2^2)
