I'll have to look at your sieve files after I get back from out of town on Mar. 13th.

OK. If you discover mistakes, then point them out to me rather than wasting your time trying to fix them (unless they are trivial).

[QUOTE=rogue;331921]Using the PrimeGrid sieve files I have pulled together the remaining n to be tested for k=19464 up to n=4000000. There are just over 4800 tests in this file. Hopefully I did this one correctly.[/QUOTE]

The file looks good. It is also for base 4. Since that is the lower base, that is where I am posting a link for it on the reservations page. k=19464 for base 16 has a referback to k=19464 for base 4.

status report
 

S10 tested till n=960000
R10 tested till n=850000

I would like to reserve

R15 3M-5M to n=25K
S15 2M-5M to n=25K

Mathew has completed R15 k=3M-5M to n=25K. 13 k's remain for the range.

S30
 

Reserving S30 to n=500K

Xentar has reported S19 complete to n=110K. 23 primes were found for n=100K-110K as follows:

Un-reserving S26. Forgot all about it. Might pick it up when I finish S30

You found a prime for it so I currently have the search depth at less than the prime. Do you know how for you went with it and if so, do you have results?

S22
 

S22 tested n=300K-500K

2 primes previously reported - 2 remain
