       Dear Robert,

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

glad to see you have found the same factors as those already known!

did you use the same polynomial used by Danilov and Popovyan?
It would be nice to compare with the polynomial found by CADO-NFS
(after a few hours of sieving you can get a quite good estimate of the ETA).

you are welcome.
