Needs about 73 digits of factors from N-1 or 218 digits from N+1 (or some combination thereof). Bit unlikely.

I was delighted to discover that factordb knew factors of 10^2059-1 and 10^2059+1 that were not known for 10^4116-1. Unfortunately, adding those is still shy of the needed factors. I think one more factor would push it high enough for a combined proof.

Nice number. :)

I´m on it.

 2018-06-24, 09:32 #368 DukeBG   Mar 2018 3×43 Posts I am also running some ecm on 1100000000587080094 and 1100000001141532029, nothing yet, but hopefully eventually...

Stopped on C4100 after 214 curves@50K and 430 curves@250K. Plus additionel 94 curves@1M.
No factor found. Now taking C588.

Stopping on C588, no factor found.

Last fiddled with by wblipp on 2018-06-25 at 13:50 Reason: Change "on" to "no"

 2018-06-25, 13:55 #372 wblipp     "William" May 2003 New Haven 22·32·5·13 Posts factordb is currently showing "submitted for N-1" thanks to vebis' P38. factordb still shows a C588, so think MisterBitcoin transposed letters and meant "no factor found" rather than "on factor found." I used my super powers to change that.

Your super power was correct; I meant "no factor found".
