lpbr is clear, but mpbr is not.

The latter is used to indicate the maximum size of composite cofactors in bits, just as lpbr is the maximum size for prime cofactors. mfp(a/r) is typically 1.5-2.0 * lpbr

Silverman, did you send the data file to Paul? I already gave instructions to my sieve machines to start sieving for the 14e application.

I'll take GW_5_345 into LA once it is done sieving. Thanks.

Reserving 135^82+82^135

ETA evening of 8 September (18.2M matrix at density 120)

I'll take GW_10_240 and C179_139_61 once sieving is compete. Thanks.

Finished last weekend, but I haven't had remote access to the server

Sort of about three days on i7/4930K with -t 6, target density 120.

Log attached; don't believe the linear-algebra elapsed time, I paused the job to run another one in the middle.
