To Paul & Emmanuel Thomé

I have successfully factored RSA-180 using Git development version 23930bb.

The overall factoring time took a total of 32 days, employing one server & nine clients, utilizing an imported poly file to save about 2 days of polysieving, in addition to running a total of 88 threads for lattice sieving, 16 threads for Krylov/Lingen/Mksol, Linear Algebra stage, & 8 threads for the sqrt run.

Many thanks for your helpful pointers in factoring this particular RSA number successfully.

Best regards,

RJD
