Happy (very late) Chinese New Year! Even though the timing was awkward this year, this 5-day SR5 challenge from 12 March 06:00 UTC to 17 March 06:00 UTC will celebrate the Year of the Rat!
We've already eliminated one K-value from the Base-5 Riesel Problem this month -- will the luck of the Rat continue?
