Largest k*2^n-1 Primes Found In 2018
Here is the list of 97 largest "Riesel" primes (k*2^n-1, k>1) found in 2018.
(Actually there had been only 97 Riesel primes submitted to the Top5000 list in 2018.) Meaning of rank marks: r1, rank on this list r2, rank on the list of all known primes (as of January 1, 2019 at 0005 GMT) Code:
