Backfilling 15k=355424355
15k.org lists a gap for 15k=355424355 between n=10000 and 170000.
In that gap you will find: 10982, 14779, 14852, 15331, 15434, 16202, 16303, 16831, 16923, 19875, 21161, 23702, 28127, 29972, 33404 Ongoing...

K55951335
I am done with this K untill forum issues are cleared up, or new project starts.
Here are all primes for K55951335 up to n=100K n=0 to 10k = 73 primes 55951335 11289 55951335 11578 55951335 11758 55951335 12712 55951335 12844 55951335 13428 55951335 14182 55951335 15692 55951335 16398 55951335 16549 55951335 17906 55951335 31544 55951335 33250 55951335 33904 55951335 43090 55951335 48710 55951335 50294 55951335 50382 55951335 55884 55951335 59910 55951335 72804 55951335 76902 55951335 81033 55951335 92671 55951335 94435 55951335 98733 (99)

3 more for 15k=355424355; now the 15k.org gap looks like this:
10982, 14779, 14852, 15331, 15434, 16202, 16303, 16831, 16923, 19875, 21161, 23702, 28127, 29972, 33404, 39315, 41043, 41592, 51211, 59238, 59772, 60612, 66268, 79481, 87840, 91514, 103375, 104433, 106609, 108981, 129800, 136851, 139247 It should be less than a week before I reach the 170000 where the 15k project started searching for bigger primes. I'm prepared to take on another similar sized gap if there are any other dense candidates deserving of a complete investigation.

k=8331405 is anther one that may be of interest. It's hundredth
prime occurs at n=45773 (#101 at 47239). It has also yielded 20 primes in the range n=186251616479 The missing gap is from n=48181181000 Larry

I shall do that next. I'll start in about 5 days, I guess, and it will take about 2 weeks. Cheers, Phil

Nevertheless, I shall do it as soon as this current batch is done (having a dry patch presently).

The first few small primes have started on my next k too, but I'll wait until I have a whole bunch before starting to post them to keep the noise down.
