Once upon a time, I had tried an idea to systematically walk through primes and find factors for Mersenne expos, but I was lagging on speed. It was simply:

How come LaurV not checking neighbouring exponents instead of a DCing the same? It seems that it prompts a TC and one cycle of DC is lost. Double check is always independent. I respect him as well,...

3607 is down
I thought that sub 10K are impossible to factor, but here it is:
"M3607 has a factor 162160065980366340636967897279169391509046358190713" (~167 bits). Unfortunately, the cofactor is not PRP :smile:.

In the process of double-checking the 900-910M range by simply factoring every exponent to 64 bits, I did not see any new factor coming bellow TF60 or any newly factored exponent. So I believe that...

Thank you very much, GP2! The range actually mattered. I am pretty sure that all exponents are "combed" to TF64, but of course some are factored to higher levels. It tells me, that the small factors...

GP2, could you check 900M-906M range? All of it is factored to TF64 for all exponents. There is only trial factoring done, so there are no Pm1 and ECM factors there. Of course not a single exponent...
