The exponent is not limited in size by my program. Instead, it is limited by Microsoft's (or the mono team's) implementation of BigInteger. Modular exponentation is extremely efficient, especially...

Whoops, that was an error on my side. I have fixed it in the attached version. I removed the one-factor-per-line-format. Instead, -v will only give additional timing and factor count information.

Yes, I can relate to that. But also the smell of winter. I have no idea how to specify that further.

For some reason, I really like the smell of pure Dimethyltryptamine and some human hormones...

No, currently, there is not. It is unlikely that there will be ever such thing because the availible work of doing CERTs is extremely limited. Since one does only a few percent of work of that...

We can do that more efficiently. Since we have [$$]\sigma(p^n)=\sum^{n-1}_{i=0}{p^i}=\frac{p^n-1}{p-1}[/$$] for prime [$]p[/$], we can check for divisors of [$]\sigma(p)[/$] as such: compute [$]p^n...
