Up up and away!

All sequences at i>=5000 are now at C>=100. :smile:[/QUOTE]

There is one just below i=5000 that has not reached C>=100: 130396 (i=4982).

Yep, I saw it earlier but hadn't gotten to i<5000 yet. As I clear out more of my old reservations, I'll start reserving some of those. In the mean time, 309480 has popped into i>5000 C<100 territory. It looks like someone (or maybe Bosma himself) may be working on it to bring it up to where Bosma presumably has it at i=5052. Right now, it's at i=5029 and C93 in the DB.

Is someone here working on bringing 309480 up to at least i=5052?

I advanced 971088 a little bit but am not reserving it. Status:

971088; i=4858; sz 108; C103; +39; 2^2*5*7

This is a random one that I picked a little while ago that was at i>4500 and C<100 because the "Fast ECM" button factored the first 2-3 indexes that were in the DB so I just tested until the hard C>=100 factor.

If you guys are OK with it, I'll do more of these "small advancements" without reserving them after making sure no one here has them reserved. That will save you some admin effort. Most of them, I end up advancing between 15 and 50 indexes over a period of a few days.

This one is effectively a long-standing 2*3 driver.

Karsten, you might want to check all of my statuses here. I think there are some that are several weeks to a month old that aren't reflected on your pages, although you're showing the pages as having been updated fairly recently.

After loss of the 2^3*3 driver at index 6575 [URL="http://factordb.com/search.php?se=1&aq=842592&action=last20&fr=0&to=0"]842592[/URL] hit the downdriver soon. Now size 129 at index 6601 running gnfs on c125.

Excellent. That is one I had advanced nearly 2400 indexes before I gave it up and you took it. Maybe you'll have a chance to go after the longest non-merging sequence < 100M to date, which is 552150 at i=8197. It's currently in 6th place, only ~40 indexes behind 5th place.

I see that the downdriver was hit at 131 digits. Does anyone know what the record high size for hitting a downdriver is?
