No curves at 260e6. 4700 curves at B1=850e6.
Just as a doublecheck, 10000 curves at 110e6 completed without finding a factor gives the following suggested curves: Code:
4400 curves with B1 = 850.0e6 2600 curves with B1 = 2.9e9 Code:
4400 curves with B1 = 850.0e6 42100 curves with B1 = 2.9e9 Last fiddled with by wombatman on 20170601 at 03:32

Thanks all for the ECM. I figured we've wasted enough cycles so I decided to do GNFS on the sequence 276 blocker.

I looked into the future and I didn't like what I saw.
There's another hundred rows with "2 * 3 * ..." in this sequence and it will be really, really boring every step of the way. So of course it is vital to drive this sequence up. Not some 2^2 * 7^2 or 2^4 * 31^2 sequence, no. Oh nonono.

So?
What is the probability of 2 * 3^2 * p203, eh?

Is anybody working on the C206?
Of course that is much over our wheelbarrow's abilities to factor, but we smell a break and we are extremely curious... We may help with sieving if guided properly
