Approaching record territory....

Seq Index Size Co-factor Driver/Guide
363270 1729 161 140 2^5 * 3
604560 2636 148 140 2^6 * 3[/code]Unfortunately, can't seem to kick the 3 on either one.....

Doubly unfortunate: looks like back-to-back c140s in my future.....

was on a trip for the last 15 days... [url=http://factordb.com/sequences.php?se=1&eff=2&aq=68067066&action=last20&fr=0&to=100]68067066[/url] is at iteration 5242, 119 digits. It has reached 120 digits and is on a downward slope now.

553014 has defeated me (for now). I picked it up at 108 digits; it rose to 110 before catching the downdriver and riding it all the way down to 57 digits, which was pretty exciting. But then it caught 2^2*7, and except for a couple promising blips it has switched from one driver to another every since. I'm leaving it after 759 terms at i1870 (size 140) = 2^4 · 3^2 · 5 · 11 · 31 · c135.

I'm also releasing 628140. It decreased briefly but after adding 364 terms, it's at i2229 (size 141) = 2^2 * 7 * c140.

680670 has been a real rollercoaster. i picked it at i595. i'm releasing it at i5294

-up to 54 digits (i615) down to 9 digits (i860).
-up to 46 then down to 39
-up to 59 down to 42 digits...
-up to 53 down to 38
-up to 63 down to 38
-up to 87 down to 74
-up to 86 down to 68
-up to 106 down to 78
-up to 91 down to 22
-up to 68 down to 44
and now its going up, 121 digits free for anyone to take. there might be a downdriver sooon (guide is 2^4*11)
