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...

Yes, I forgot to mention it explicitly, the base can be any whole number from 2 to 1060, currently, but this might be expandable with some additional code.

Wait a bit, please. I greatly overcomplicated what needs to be done and there are (at least...) two errors in the last formula I posted. I'll update you when I have a running program. It is already...

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...

There are still quite a few DC's to be done between 11M and 15M, suprisingly. But not enough to really worry about.
That exponent only had one test and a CERT, so I guess it was a FTC and not...
