Hmm, my calculations say it would probably take well over a month to take an exponent up to 71 bits. How about a shallower bit depth? Can I use set a bit depth that is not an integer? (Sorry I'm asking so many questions non-stop).

Each bit takes twice as long as the previous one, and things get pretty slow above 70 bits, expecially with slow computers the P-pro 180 I'm using. There are still many unclaimed exponents at 65 bits on [url]http://ElevenSmooth.com/Billion.html[/url].

Remember this is a whimsical project - there is no hope of getting beyond the trial factoring stage. So pick something for the silly fun of doing it and don't worry much about what.

3321928699 no factor from 66 to 67 bits.

True, but that does not mean we don't need effective management. I believe we should not go beyond 3321929879 until every previous digit is factored to at least 60 bits.

Has somebody tested this for 65 to 66?

I think that this is one of those little errors that you had on your site. My spreadsheet showed it to be at 66 (I think that I did it). I will DC my mind.

I could not locate a result for xx699 between 65 and 66, so to be on the safe side I am running it. Should have an answer by 2pm GMT Friday or sooner.

OK. I didn't anywhere it had been posted.

clowns,

Should I mark this "active" to warn other people away, or are you finished with exponent for now?

Except for those near the end of the current range that have factors, all have been taken to at least 60 bits. All with out a factor are at 65 or above..

Is it possible to force the program to write a save file (as in when I'm about to turn off the computer)? I've noticed that it doesn't always write a save file when I push Ctrl-c.

No factors found.


BTW, I am taking 3321928307 up to 72 (against my desire to do more to lower levels).
