Releasing 170562, 134 Digits, 2^3*3*5^2

This sequence used the 5^2 to change the factor of 3 from 3^2 to 3. I don't think 2^3*3^2*5 has a driver because changing the 2 value and changing the 3 value from 3^2 to 3 both require the 5^2 to have a chance. Since it gets stuck at 3^2, it has an increased chance of escaping compared to a driver.

[QUOTE=schickel;263335]Just did a complete status update for the first post. Unfortunately, just one active downdriver showing this time. :sad:[/QUOTE]

752976 now has an active downdriver

I would like to reserve 99850, its not on the list and
[url]http://www.rieselprime.de/Others/Aliquot000.htm[/url] shows it as unreserved.

AliSeq 99850 is not on my summary page at the above link and therefore already solved.

The [url=http://factordb.com/sequences.php?se=1&eff=2&aq=99850&action=last&fr=0&to=100]FactorDB Aliqout sequence 99850[/url] shows it terminates after 182 indices in p=37, so nothing to do for this one.

[Scratch that....Greebley's got 98850 reserved.] Anything else look tempting? How big a range of composites are you able to tackle?

Sorry, typo: Should be 99840, which seems unassigned, and the factor DB shows a nice C105.

Is there any chance to get rid of driver on [URL="http://factordb.com/sequences.php?se=1&aq=283752&action=last20"]283752[/URL]?

Releasing 115626. It picked up the 2^2*7 driver. I got it over 120 digits and stopped.

I can email Clifford to ask him what the odds are.

I'm actually interested in [URL="http://factordb.com/sequences.php?se=1&eff=2&aq=660&action=last20&fr=0&to=100"]660[/URL] also, since on the current line it is [TEX]2^33^25 * c178[/TEX]. If the c178 has the proper form, there is a chance of escape from the driver for that one also.

283752 has a 1/2 chance of escape: the c156 is 1 mod 4, so if it splits into 2 1 mod 4 factors it will escape, otherwise it won't.
660 can't escape as both factors would have to be 1 mod 4, but the c178 is 3 mod 4 so that isn't possible.
