Thusfar, I've found 6 new factors in the 79K,80K,81K ranges using B1=1e12, B2=20e15.

I'm reserving ranges 76K,77K,78K.

I found 2 biggish factors -- 129 & 134 bits -- in my first batch of exponents in the 14k range:

M14321 Factor: 1227402003319228348725041527104377980649 / (P-1, B1=1000000000, B2=3088390743498060)
M14387 Factor: 27562343134739559423772046255780767094401 / (P-1, B1=1000000000, B2=3088390743498060)

I've been haphazardly poking around in the 1k and 4-5k regions as well and plan to finish up 14k.

Ethan I would suggest not working below 8K, those numbers have had substantial ECM by Ryan and I would be amazed if you found any factor below 200 bits.

Thanks for the heads-up - Iโ€™ll stick to 8k+ after runs in progress wrap up ๐Ÿ‘

I'm wrapping up this range, found at least 4 new factors.

Reserving 75K.

And a bit of Beethoven.

And a bit of silence.

To be sincere. I greatly enjoy silence.

Default Avoiding toe stepping...

Work is starting on the next P-1 project taking advantage of v30.8 here
I'm hoping/expecting it will pick up in the next couple weeks as the under 2000 warps up.

At the highest level it's goals are very similar to this project: taking advantage of the power of v30.8 to find LOTS of P-1 factors.

That said, no one in either project wants to get in the way of the other (i.e. working in the same exponent ranges).
Neither project has a lot of effort/assignees but we still want to respect each other.

I will try to maintain an "assigned" list in Post #1 of the project noted above.
I've noticed post #98 mentions some "claims" in this project.

If this project wants to stake claim to every exponent under, say 100K?, I'm sure we can respect that.

I can tell from recent activity that there is more independent P-1 activity but I suggest that is the nature of the beast. We have no right to say what anyone can or cannot work on. That we will live with.

I welcome any thoughts.

Wayne

M36919 has a 180.968-bit (55-digit) factor: 2997347544642661833497896836795494793702018162645139063 (P-1,B1=2000000000,B2=401927737170960)


That gets me to the top of the list of P-1 factors for Mersenne numbers! And all thanks to the new version 30.8 of mprime.
