How large a factor can P1 testing find ?
In trial factoring for the bigger mersennes it will test factors that are upto 72 bits long ( to just below 2^72 ).
The software may support slighty higher for factor overide but not sure about it.
What is the max size factor P1 factoring can find in either stage 1 or stage 2 ?
Why is that ( whatever it is ) the limit ? memory, software, math ?
Perhaps, this is also a math question.
