[URL="http://factordb.com/search.php?se=1&aq=807612&action=last20&fr=&to="]807612[/URL] is finished: size 101, i2239, 2[sup]3[/sup] * 5[sup]2[/sup] * 151 * c96

But, this one was a fun ride (adding 890 iterations), which bears some extra text. It might even prove interesting for the next time...

First, I picked it up on a slow upswing to 91 digits (i1348), mostly carrying 2[sup]2[/sup] * 7, with a few minor variances.
At 91 digits (i1470-i1495), it dropped the 7 and the extra powers of 2 and ran all the way down to 65 digits.
At i1635 it picked up more powers of 2 and kept falling until it reached 61 digits at i1676, where it picked up some 3's.
Then it climbed all the way to 99 digits (i1945), got scrared, shed the 3 and ran downhill to 77 digits (i2091) before picking up the 3 again.
This time, even though it later shed the 3, it finally succeeded in reaching the subproject goal. I wonder if there is another downswing in its near future...

I know this type of action is "old hat" to many of you, but I'm still a novice, and therefore, easily entertained.

In case I've been confusing in my interest, I am releasing this number totally.

Take Care,
Ed

You might find out soon...
I need another sequence because of 2 sequences getting 2^3 * 3(one also has a 5).
I will reserve this one because it has nice history.

Still searching for my first termination.
That's partly because i like searching higher than 100 digits as well:smile:.

I'd like to take 880k-890k (67 seqs)!?

[URL="http://factordb.com/search.php?se=1&aq=807834&action=last20&fr=&to="]807834[/URL] is finished: size 102, i668, 2[sup]2[/sup] * 3 * 5 * 13 * 29 * 198839 * 5799557361849289 * c77

I'm glad to see someone was interested in 807612. I'll have to check it out now and then to see if it has another dip, or two, or...

That's the third termination today! Just to (hopefully) join in on the fun...

The same thing I said here applies :smile::[quote=Mini-Geek;205488]I don't mind. Might want to wait for 10metreh to OK it before you start.
If you do this, please provide dates (assuming GMT time zone) for starting and stopping each 5k section. And you should check each one with the DB to make sure that it's not already at 100 digits.[/quote]

more progress
 
23/78 sequences finished (all at 100 digits; no terminations) in the 890k-900k range. At this moment, 21 gnfs-lasieve (C85 or bigger), 14 msieve (9 mpqs, 4 polsel, 1 linalg), and 20 ECM (which I run for 1/2 the time that I expect a guaranteed-to-finish protocol to take).
