The WUs for part 4 should take 5-6 months to process at the current speed. So maybe you will be able to get to 1 billion :)

What I'm hearing is when Part 4 of 10^21 is finished, Amicable Numbers will most likely be finished. IF I person is trying to obtain a badge, they have about 6 months to obtain it. Due to the time to complete 10^22, there are no plans to initiate 10^22.

I would like to thank you for all your efforts with 10^20 and 10^21. I also appreciate your thoroughness. GOOD JOB!

Bonjour,
La partie 3 arrive à sa fin.
Quelle va être la suite du programme?
Une partie 4?
Ou continuons-nous une autre tranche de calcul?
Outre autre chose!?
Cordialement,

There will be part 4 and it will take approximately 6 months. There are no other plans after that, so the project will most likely finish.

I didn't think it was too difficult to understand.

I remember crunching Amicable Numbers years ago on a 1050 Ti. It's awesome to see the project come to a close possibly in 2026.
