The seventh challenge of the 2020 Series will be a 5-day challenge celebrating the 209th birthday of Évariste Galois, French mathematician and political activist. The challenge will be offered on the PPS-DIV (LLR) application, beginning 20 October 06:00 UTC and ending 25 October 06:00 UTC. To participate in the Challenge, please select only the Fermat Divisor Search LLR (PPS-DIV) project in your PrimeGrid preferences section. Work units which are downloaded and completed during the challenge will count towards your challenge score. Note: This will be our first challenge using LLR2, which eliminates the need for a full doublecheck task on each workunit, but replaces it with a short verification task. Expect to receive a few tasks about 1% of normal length. Please see this important warning about task bunkering. Riddles? Requests? Reservations? Tell us in the forum thread for this challenge. Best of luck!
