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!
