That was suggested to Pepi in the sieving thread. Our big sieve for goal #4 was holding it up. It shouldn't be much longer before it starts.

Happy,

From a year ago...was this done? I'd like to go ahead and double-check k=14549535 for all n<=300K and then test it up to n=500K. Is that OK?

rsp4M = 3M to 4M
rsp5M = 4M to 5M
rsp6M = 5M to 6M

It is n=3M to 6M that are sieved to 400e15.
(n=0 to 3M are sieved to 100e15.)

Ignore the header line in the sieve file. It means nothing. ...

You should use the PrimeGrid sieve file for testing. All k<10000 for n=1 to 3M are sieved to P=100P (100e15). The file will save you a lot of time in sieving and testing.
