Thanks for explaining. I missed the fact that there is a random parameter involved...

Though I still think it would be nice if PrimeNet manual testing page did not assign tasks of different type than I asked for.

As for this exponent, mfaktc, which I planned to use, doesn't even support trial factoring for exponents lower than 100K. As well as non-prime exponents for some reason (I wanted to overcome the 100K limit by trial factoring M163456 = M(2

^{7}*1277), which is a product of M1277, and looking if there are any new factors between

2113601438322189019 < 2^65 and 2^80 <

1227156720026097481648213, both of which are consecutive

factors of M163456).
