That's fine. Activity has been low, so there is very little risk of poaching.

Taking S864 to n=100k.

It would be nice if the forum supported .7z files in addition to the other file types. .7z seems to compress better than .zip.

[TheCount]

132*678^78513+1 is prime!
So I've transmuted a 3k'er into a 1k'er.

S678 is now complete to n=100k and released.
171*678^60397+1 previously reported prime.
S678 Residues.zip

[TheCount]

15*864^51510+1 is prime! That makes S864 a 3k'er.

Early win.

[Puzzle-Peter]

tested n=600k to 700k, no primes. Continuing...

[TheCount]

53*864^56085+1 is prime! S864 is now a 2k'er.

This base is really paying out.
Found k's (15, 53) had 35% and 53% chance respectively of prime 50-150k.
Remaining k's (74, 136) are still good chances at 34% and 26% of prime 50-150k.

Firejuggler,

This submission has problems:

1. Please reserve an even k-range such as k=5000-10000 in the future. It makes it easier to show on the pages.

2. Please observe what k's you are searching. You have attached multiple primes for k's that already have primes in your previous search up to n=10K for the entire base. The first 5 of them are shown below. There are many more. This makes it difficult for me to sort out what is correct.

Primes for k's already found prime (previous prime)
7529*592^10027-1 (n=4567)
6192*592^10177-1 (n=8158)
9209*592^10564-1 (n=4273)
6848*592^11196-1 (n=3303)
7655*592^12640-1 (n=8079)
[and many more]

Because this is so problamatic for me to spend any more time on and makes me question the accuracy of your testing methods, I am going to request that you re-run the range before I can reflect it on the pages. I will also need all of the residues. If you do so, please test up to k=10K. I will unreserve the base until I hear otherwise from you.

Edit: To make it easier, I have removed all n-values <10K and all k's that already have primes for n<10K from the sieve file.

You take all the bases with mostly composites so that TheCount and others can take all the bases with mostly primes.
