There are thousands of exponents that have no "no" or "PRP" in that range, so the result is unknown from the point of view of the database.

Oh, I see what you mean. Mea culpa. Assuming all is working as intended, the only apparent cause, then, is that they're reserved to be PRP tested. It says the reservations last for 7 days, so they should soon be complete or available for reservation.

I've just found a complete factorization:
M576551 = 4612409 x 64758208321 x 242584327930759 x PRP173528

And here is another: 2^{2[sup]26}[/sup]1. All numbers presented here meet the definition of a Mersenne number as specified in the current title "New mersenne number completely factorized".

probable 1. likely to occur or prove true 2. having more evidence for than against, or evidence that inclines the mind to belief but leaves some room for doubt. 3. affording ground for belief. So by definition, it is not completely factored.

This equals (2^2^251)(2^2^25+1). Since when F25 is full factored? Last fiddled with by LaurV on 20140614 at 09:32
