One more reminder of the follow-up project.
With this project expected to complete in a couple days...
and if you still want to use the power of v30.8 to find lots of P-1 factors in low ranges...
see the TL;DR summary to the follow-up project [URL=""]here.[/URL]

This project will complete in several hours……
Only 5 factors left, and tomorrow morning it will be done.

Maybe. Maybe not.

4 years 8 months 21 days.

4 years 8 months 25 days.

Same difference.

I'm expecting the Easter Bunny will find the last factor.

Wouldn't the Easter Bunny hide it instead?

Not if he doesn't want to be stew.

Last one!
I bet that factor will be found in minutes:bounce wave:

Let the party begin!!!!
The last factor in this project was found at: 2022-04-16 03:07 UTC (by me :blush:)

What was initially anticipated to take me 685 years (i.e. NEVER) was completed in 1,727 days; about 4.75 years.

Over these almost 5 years "the collective" found close to 60,000 factors.
On 2017/07/24 I initially identified 497 ranges under 60M that needed clearing.
Along with these there were about 28 other stubborn ranges from 60M to 108.3M that got caught up in our vortex.
In other words the help I received was beyond amazing.

I am truly afraid to start noting all the help I received as I know I'm going to forget something or someone.
And for that reason I will (in most cases) avoid names and still I will apologize in advance to anyone who feels missed.

1. Many of you for valuable advice regarding parameters, settings, methods, techniques, etc. that saved all of us time and frustration
2. Over time more and more of you offered your CPU's and GPU's. I suspect what was initially seen as a whimsical silly pipe-dream slowly gathered (A LOT OF!!!) steam and interest.
--- A few of you offered some mind blowing GPU capacity to TF away thousands of factors.
3. I do need to mention @Chris for all the ways he supported us including:
--- Setting up the TWOK web page to track progress
--- The time and energy to enable colab to encourage, gather, manage and simplify for those who chose to get involved.
4. @George for the incredible speed-up in P-1 processing under v30.8. Even though this version only come to be less than 5 months ago I estimate it saved this project about 1 year elapsed time.


I cannot thank each and every one of you enough.

P.S. I humbly reserve the right to add to this as I realize my oversights (5 years is way, way beyond my senior memory capabilities.)

It has been good fun. Thanks for this challenge. I still look forward to the goal stated in the title of this thread: getting to less than 20M unfactored. I acknoledge it will be a really tough one, but... who knows what this communnity will be able to achieve? :smile:

All times are UTC. The time now is 19:55.
