A peaceful night for you,

is it possible to add a button for the search with next exponent without factor and untested
under mersenne.ca/exponent/ ?

Would be helpful for me and I think also for other persons.

Thanks for your work.



P.S. The energy prices are falling and the question is, when will the power companies decrease also their prices.

There's already buttons for next/previous: (< exponent >), (<< exponent with factor >>), (<! exponent without factor !>), (<<< Mersenne Prime >>>)

Ah okay, makes more sense now. Doing it this way would prevent cases where the P-1 bounds are fine but the TF is absurd from showing up on the poorly factored page when in fact they have been factored just fine. The downside is that for exponents where TJAOI limit is above the PrimeNet default they wouldn't show up since their probability is >20% with default TF but this is a minority of cases.

After all, this is meant to be a list of "poorly factored exponents" and not a page that sorts exponents by actual P-1 probability, especially in ranges where there are no poorly factored exponents.
