PrimeGrid Better Late Than Never: 2017 Tour de Primes!

PrimeGrid's annual Tour de Primes is underway! Unlike other challenges, there's no trophy for participation. This challenge is all about finding prime numbers. As with last year, there will also be a red jersey -- which will be awarded to whomever finds the largest prime number during the month of February. And, of course, we'll be awarding the green, yellow, and polk-a-dot jerseys as in previous years. For more information, please see Tour de Primes 2017. Good luck everyone!
