Now, on with a c135...

I'm sorry if my comment above led to this.

I find that unlikely:[quote=mataje;188427]I will do 6 numbers in the 450k-500k range (455004, 455340, 478440, 483246, 493512 and 493830) and then, STOP. I´ll take a break.[/quote]

[quote=henryzz;188388]finally after hanging around so long at ~115 digits with numerous >c110 factorizations 157752 has gained the downdriver:party:[/quote]
157752 has been through a lot of down drivers with many ups and downs over the last few days. In fact it has been bounding up and down so much that it has put on 3200 lines in less than a week and now has over 4000 lines. That means it has now earned a place [URL="http://mersenneforum.org/showthread.php?t=11804"]here[/URL].

I have noticed that 162126 has overtaken 564 as the highest sequence: it is now at 166 digits. It has 2^3 * 3 * 5 and a c157, though, much worse that 4788... :cry:

I am now done with 153090. Status:

153090; i=629; sz 109; C103; +49; 2^4


With no small factors other than 2^4, some folks might like this one. :smile: I got rid of the factor of 3 about 15 indexes back.

I'll continue with 153090. How much ECM work are done?

[quote=unconnected;189085]I'll continue with 153090. How much ECM work are done?[/quote]

The default amount by aliqueit.exe for the C103:
74 curves at B=11K
214 curves at B=50K
430 curves at B=250K
885 curves at B=1M

I didn't run any GNFS so you could start with that.

It would be nice if the DB would at least do SOME work other than the "quick ECM". As far as I can tell, there are no workers (other than enough to do the quick ECMs) and there have not been any for at least 2 weeks. It even repaired some sequences that I ask it to a little while back but now it is no longer even doing that.

I am now done with 13800. Status:

This one is definitely NOT interesting!
