[quote=XYYXF]C203_125_51
6375*(5^25)^6 + (51^21)^6 = 1910750658792*C203

C229_125_81
125*(5^40)^6 + 9*(3^83)^6 = 6306078046*C229

Both survived 7600@43M.[/quote]
C203_125_51 is an easy one (SNFS ~214) and has already received more than enough ECM, so I guess I can reserve it :wink:
However, with a SNFS difficulty near 239, for good measure, C229_125_81 needs, say, 3t50 before NFS@Home can sieve it.

I'll take GW_5_311 thanks. I'm aware it is ready for downloading I will start to download the.DAT file in approximately 14 hours from time of this post.

It looks as if progress has pretty much stalled on C176_3270_677 (the number of unsent blocks has actually gone up since this morning), so I'm grabbing the .dat.gz file now and will start linear algebra later tonight.

PS: ETA Monday morning

GC_6_279 is complete

Thanks, but can I ask you to [URL="mailto:paul@leyland.vispa.com"]mail me[/URL] the results as well as post them here please? They are much less likely to be overlooked.

Can I please reserve W_2_818 If pending refs have moved from 1408473 I will start download in the morning. I think there has been sitting at this number for a period of time, the file is 12 gig

Refs are moving down so I'll wait until it reaches 0. Currently at 956457

I will ECM C229_125_81 to the t55 level if that would be sufficient.

t55 for a SNFS difficulty 239 is a bit above the 2/9 rule of thumb. You could do a bit less than that, say 14K curves at B1=11e7 :smile:

C203_125_51 now queued for sieving at NFS@Home.

Ok thanks, I'll start ECM next week, will report results in this thread.
