What is LLR and do we automatically have it or do we need to download it.
It would save me perhaps a lot of time if someone would point me in the right direction. Thanks.

LLR: https://en.wikipedia.org/wiki/Lucas%E2%80%93Lehmer%E2%80%93Riesel_test

It's also the name of the program that implements the LLR algorithm. We use LLR to test the primality of many large numbers. It's downloaded automatically when an LLR task is sent to your computer.

In the project preferences web page, you select which projects you want to run. In the order they appear on the page, there's AP27, a dozen LLR projects, 2 sieve projects, and 9 GFN projects.

Please do not PM me with support questions. Ask on the forums instead. Thank you!
