Here is the last one (5 files upload limit)

[Grotex]

Reserving base 74 to n = 80k.

[dacat]

Reserving base 158 from n=10k to 30k

CK290 at n=157k
CK362 still at n=139k
and cointinuing.

Make it official, reserving bases with no primes on Carol side:
CK688 at n=64k
CK968 at n=69k
CK1286 at n=59k
CK1346 at n=57k

For bases 688, 968, 1286, and 1346 are you searching both the Carol and Kynea sides? If so are there any Kynea primes? If so please report them. Thanks.

The web page is not set up for searching on only one side.

There are also smaller base without a Carol prime:

640, 702, 738, 832, 866, 928, 938, 942, 950, 964, 992, 1032, 1068, 1108, 1132, 1152, 1188, ...

Not quite, some are with found primes (example base=866) , see the pages in the Wiki for bases without Carol or Kynea (or both).
All bases like those are with their own page and data/history.

All other bases <=3000 are listed with primes up to n=2000 in a separate file/table.

I added the second link here to the first post of this thread. I've chosen not to add some bases > 500 to the main page if they were not reserved in this thread although many that were reserved in these threads are shown. I may eventually add all your data up to base 1000.

[dacat]

Searched base 154 from 10k - 30k and found no primes.

Searched base 158 from 10k - 20k and found no primes. 20-30k still in progress.

Sieve files attached.

[dacat]

Base 158 from 20k - 30k is finished. No primes found.
Base 160 from 10k - 30k searched with no primes found also.

I'll continue on with base 158 , 30k - 40k.

[dacat]

Base 156 from 20k - 30k was completed.

Found (156^24434+1)^2-2 is prime (107174 digits)
Found (156^27423+1)^2-2 is prime (120285 digits)
