What is YAFU?

YAFU's goal is to factorize numbers up to 149 digit length which are needed to bring Aliquot Sequences to a size of at least 140. You can participate by downloading and running a free program on your computer.
The project runs without any funding and I'm happy about each donation.
The invitation code for creating new accounts is yafu
