Then maybe this one?

[b]C225_144_86[/b], 7600 curves at B1=43M
Sextic (difficulty 235): 324*(2[sup]33[/sup]*3[sup]28[/sup])[sup]6[/sup] + (43[sup]24[/sup])[sup]6[/sup] = 50058674209 * C225

William: is the polynomial with big coefficients you're talking about the one I can get from FactorDB's automated system ? Do you have a sextic for that ?

Sean: I usually expect over t50 for SNFS difficulty 235 numbers, given that 225*2/9 = 50. Thanks for your offer, but for once, I should be able to handle the extra ECM work on that particular number using "my" resources :smile:
Yesterday evening, I started 2x8+4x4 ecmclient instances. They ran nearly 3500 curves at B1=43e6 (no B1=11e7 for them due to memory constraints) in about 10h, so I should have a bit over t50 by tonight, and be able to cut them either tonight, or tomorrow morning.

Andrey: yup, provided it receives another at least another t50 ECM work, per the above. Say, 4000 @ B1=11e7 ?

I'll run this for another 4000 curves a@B1=11e7.

Since 31 = 5*6+1, the quintic and sextic are nearly the same. For

2426789^31+3162104763

They are

2426789*x^a + 3162104763 with x=2426789^b

(a,b) = (6,5) gives the sextic, (a,b)=(5,6) gives the quintic.

[QUOTE=wombatman;426907]Just wanted to follow up and see if the C190 for Home Primes 2 (4496) from [URL="http://www.mersenneforum.org/showpost.php?p=425167&postcount=365"]this[/URL] post is a good candidate for NFS@Home?

Thanks! :smile:[/QUOTE]

Bumpity bump! :whistle:

C189_147_41
 
[QUOTE=swellman;426399]Sorry if it breaks 14e on the -a side. It can be sieved on the -r side without crash in Windows and the yield/speed isn't horrible and still suitable for 14e (i.e. months on an individual machine).[/QUOTE]

Cough, bump, beg...
:help:

I have queued C189_147_41 (Sean) and C186_2426789_31_plus_3162104763 (William).

Sean: I'll queue C225_144_86 when ECM is finished, and I can queue C162_145_107, unless you plan on doing it ?

Ben: ping Greg and Tom :wink:

swellman 2016-03-05 11:42

Lionel,

Appreciate you queuing these. If you would also queue C162_145_107 it would be very helpful. A [url=http://www.mersenneforum.org/showpost.php?p=428159&postcount=535]poly can be found here[/url].

ECM of C225_144_86 should be completed by midweek.

Thanks!

debrouxl 2016-03-05 15:31

Alright, queued C162_145_107.

Given that the 14e queue is quite short, I think I'll revert to queuing several SNFS difficulty 225-235 numbers, even if they're more work for me and don't feed the grid for long...
I've just reserved several near-repdigit numbers on which I'll handle ECM by myself, and I will also queue the two following XYYXF numbers suggested above:
C172_145_36
C213_150_38

[QUOTE=debrouxl;428169]I'll revert to queuing several SNFS difficulty 225-235[/QUOTE]

If you want more this small, these two are ready

727^91-1

use x^6 + x^5 + x^ + x^3 + x^2 + x + 1
z = 727^13

-------------------
5519^59-1

Are you interested in going below 155 for GNFS? I have 3 at C152 and 2 at C149.
