k=213 is complete to n=2M; 3 previously found primes confirmed and no new primes for n=1M2M; the k is released.
Primes/residues added to doublecheck thread post #70. All k<400 are now at n>=2M. :) Last fiddled with by gd_barnes on 20210327 at 05:48

Trilo, From July 2017...are you still working on k=59 and 75? If so can you provide an update? Thanks. Gary Last fiddled with by gd_barnes on 20210428 at 05:37

After several attempts to contact Kosmaj followed by a several week wait and a discussion with Dave and Thomas, it was decided to release Kosmaj's reservations for k=7, 21, and 77.
Therefore: Reserving k=7 to n=5M including a doublecheck for n=1M4.23M. Reserving k=21 to n=3.5M including a doublecheck for n=1M2.89M. Doublechecking for k=7 is already at n=~4.07M and will be done to n=4.23M in 34 days...then continuing to n=5M. No primes found. k=77 is available with a test limit of n=2.18M.

k=7 is complete to n=5M; doublecheck is complete for n=1M4.23M. No primes found for n=1M5M. The k is released. Results attached.
This is likely the longest currently running nrange without a prime for k<300.
