After more than 6 years, the BOINC project to find all amicable numbers up to 10²¹ is finished!

There are 4,810,863 21-digit amicable numbers, and 4,661,814 (96.9%) of them were found by BOINC volunteers. More than 60 million WUs were created and crunched through over the years.

Congratulations everyone and thank you all for your participation!

There are no plans to run the search up to 10²² at the moment - it will take more than 60 years, which is impractical. If, and that's a big IF, a new more efficient exhaustive search method is discovered in the future, then it will make sense to start the project again.

Dans la vie il faut être audacieux. C'est pourquoi nous devrions par ton aide commencer à calculer 10^22
Tout évolue à grande vitesse. L'estimation est de 60 ans mais nous pourrons pour sûr le terminer avant...
Je reste persuadé que 90% des participants boinc sont prêt et excité à relever le défi.
Sergei Chernykh lance les unité de calculs. Nous sommes prêt.

Would the improvement in hardware each year impact that 60 year timeline for a new search?

You bet it does! What could you do with a computer 60 years ago, in 1966? What was the progress in computer power over those years? No reason the suspect we are now at a stand still. As soon as photonic CPUs become available to the public we can expect a next massive leap in desktop processing power, let alone the advent of quantum CPUs.
