Factoring for a publication

Well, actually, it wasn't as bad as I thought. I was looking at the wrong params file. I found the correct one that I used (even has I = 14), but I see I didn't tell it the rational side. Does it default to algebraic?

Edit: I'm still going to take a break. . .

Yes it does, as it is geared towards GNFS. You need tasks.sieve.sqside = 0 to make it sieve on the rational side.

I've gotten in the habit of automating too many things with scripts. When I go back to manual, I forget things, especially when they are in the basic params files..

On the positive side, line 243 (12, 5) is finished:

c156 = p76 * p80

CADO-NFS failed, but Msieve picked up the slack.

Finally, after much help from Max and EdH, the C151 from (1,10) has factored as:

p60 factor: 184806081306587174940291557245764342530914498190952548289121
p92 factor: 35962122580466008384842772124308061023691332262402425391674828016485830052008927622384358809

[wombatman]

The C177 from (12,4) is done:

p83 factor: 43946310278493822373729067976053173025156013123463695922015864334758076849073761041
p94 factor: 3879640675160979541328532833157840602964785213307428969835564939629208135592552250176921248367

+14.9%, very close E scores, for wombatman:
