reserving GC_8_274
 

Taking [B]GC_8_274 [/B]for post-processsing, will start downloading tonight (UTC+1), as my connection is more stable then.

Taking GC_9_256.

[QUOTE=swellman;390126][url=http://factordb.com/index.php?id=1100000000041784360]p65*p110[/url][/QUOTE]Thanks.

Snarfed the number from here because my ISP's mail server is playing silly buggers ATM.

I've gone ahead and downloaded the HomePrimes C158 relations. It's starting with density 130.

Matrix was 5.36M, density was 130, and 6 threads were used.

L1923 and L1926
 

I'm reserving L1923 and L1926, if they are still available.
I've already downloaded the relations and started filtering, but I will not start LA untill after Christmas. Depending on the sizes of the matrices they will probably finish mid-to-end of January.

If anybody still wants to do one of these two, let me know. But since they have been waiting for somebody to pick them up for post-processing for some time now, I'd doubt that.
