No Prime Left Behind
No Prime Left Behind is a prime searching project started on 2008-01-10. The project searches for Riesel primes of the form k•2n-1 with odd k and 300 < k < 1001 and n > 260.000 not reserved by others with highly presieved ranges.
It was intended to continue the Primesearch project. Gary Barnes and Karsten Bonath both independently begun to sieve and search the old ranges in 2007 and 2008.
