Thank you for explanation.

296886 digested some other sequence (didn't check what, yet, 1:00AM here, going to bed) but the last 60 terms or so popped up instantly from fdb, after we reported previous terms.

[URL="http://factordb.com/sequences.php?se=1&aq=2035656&action=last&fr=0&to=100"]2035656[/URL] merges with [URL="http://factordb.com/sequences.php?se=1&aq=296886&action=last&fr=0&to=100"]296886[/URL], so you should continue working on 296886.

Cool result, though! :tu:
The merge is far from trivial -->

[CODE]2035656.elf: 468 . 7870940 = 2^2 * 5 * 7 * 11 * 19 * 269
296886.elf: 2218 . 7870940 = 2^2 * 5 * 7 * 11 * 19 * 269[/CODE]

Ok, cool! Thanks. I will continue with it until it terminates or it gets over the former top (142+ digits) [U]and[/U] has a driver.
I assumed it was a higher-starter, because of the 120+ digits of the last term, that is why I said "digested" and not "merged" (most 6-digit-starters are worked higher than 120 digits).
