I've started the team sieve thread, so we can do our poly search discussion/coordinating in there now.

78@43M, no factor.

So, we have a new line, but the 2^7 * 3^2 * 17 is still there. There is a C137 as well...

I did 2000 curves @ B1=3e6, B2=default on the c137. No factor.

 Andi47 2009-05-28 05:45

I did 98 ECM curves at B1=43e6 overnight (B2 = default), no factor.

Can you report your results [URL="http://factorization.ath.cx/search.php?id=38898191&eff=true&detail=1"]here[/URL]?

My analysis shows that, assuming a 2-way split, we have a 50-50 chance of losing the 2^7 in this iteration!
[Currently, there are enough factors to assure 2^4. There is a 50-50 chance of getting > 2^3 from the remaining factors (from the c137) which will guarantee that 2^7 will persist.]

EDIT:- A 3-way split will however guarantee that 2^7 persists :-(
