Releasing 280686.

Reserving 13524, 13800, 14190, 14280, and 15390.

Releasing 14280 after advancing it 2 indexes. Karsten gave me a heads up that Clifford is still working on it.

Karsten, do you want to give the admins here a list of what Clifford has reserved for 10K-30K so that they can show it in the 1st post? That is the range of files we have received from him.

I found another promising sequence
[URL="http://factordb.com/search.php?query=&se=1&aq=552150"]552150[/URL] (taking at 3964, now at 5311)
Let's see where this wormhole goes...

Was trying to get 699000 to 80 digits and next time I looked it was up to 98. Consider it reserved - I will take to 100 at least.

gd_barnes 2009-07-29 02:21

Releasing 10824 and 14022.

Reserving 18102, 19128, 19278, 19680, and 40404.

It didn't take me long to find a sequence that most definitely will top 280686 as the longest ever-increasing sequence: 19278 above.

280686 made it to i=946 with a size of 109 before I abandoned it with a hard C102. 19278 is already at i=944 and has a size of only 100. After dropping a factor of 5 at i=935 and then again at i=937, it is increasing VERY slowly with no other small factors then 2*3 right now. It is only up a grand total of 20% in the last 7 indexes. Like 280686, it has never let go of 2*3 but has much more rarely picked up higher powers of 2 and 3 before dropping them fairly quickly. This should be interesting. Actually, it would be more interesting if would get to i=1000, then drop the factor of 3, and then terminate. :-)

Seq 81882
 
I've taken seq 81882 several (many) steps and it is starting a downward trend. If someone wants to jump on this seq to see where it goes, feel free. I'm not going to have any time in the coming weeks.

81882
 
I'll give it a try.

Giving up on a downdriver run? Wow. That's what we all want. Good luck Batalov!

In the mean time:

Releasing 20088.

Reserving 17040, 18960, 19110, and 19248.

Batalov 2009-07-30 08:32

No it was a 2[sup]2[/sup] for another 20 iterations. Downdriver is mine. :-)

gd_barnes 2009-07-30 10:42

Ah, good deal on catching the downdriver so quickly.

In other news: I'm now releasing 108408. It got all the way up to a size of 121 before hitting a hard C>=100 factor. There are many factors on that rapidly increasing sequence.
