Comment:
thank you Frederic for your review. For {{{ecmfactor(2^167-1, 2e5)}}} the
7-digit factor is always found by ECM since the curve has order divisible
by 12 at least. However the 44-digit factor might be found in some (very)
rare cases, which was the reason for the "random" keyword. The other cases
are fine.
Paul
