I'm nearly half of the way through the hole
k=8331405: 49415 50445 52637 56391 64400 84059 85434 132909 Nice start, shame about the latter dearth. Phil

For k=736320585 I have reached n=410k... so far 99 primes have been discovered, I am still looking for #100
BTW: Maybe we should move this thread to "RPS  forum"

Brave chappy! It'll be there eventually, of course, and it will hopefully be worth the wait. Good luck with that. Regarding thread location  I have no strong opinion. On a side note, due to a catastrophic machine failure last week, I'll not be able to do any more small prime backfilling for a while, as I need to move the machine I was using onto sieving. However, it did appear that there weren't any obvious holes in the absolute densest (appearing) candidates.

8331405 backfilled completely
15k=8331405's hole contained 9 primes:
49415, 50445, 52637, 56391, 64400, 84059, 85434, 132909, 163192 (I had a few problems with LLR in the middle of that, if anyone would like to have my lresults.txt file, and perhaps doublecheck the 85434132909 region, then just ask.) Can somebody ensure 15k.org is updated? The full list now stands at 132: 1, 9, 11, 17, 21, 31, 32, 33, 45, 57, 61, 64, 67, 69, 77, 80, 85, 88, 107, 115, 117, 120, 121, 124, 147, 155, 161, 164, 168, 177, 179, 221, 232, 258, 261, 264, 281, 282, 299, 308, 342, 415, 471, 503, 504, 505, 537, 572, 680, 989, 1328, 1565, 1607, 1613, 1841, 1953, 2509, 2692, 2739, 2834, 3627, 3735, 3870, 3960, 4083, 4682, 4788, 5187, 5247, 5623, 5804, 6015, 6020, 6405, 6569, 7052, 7315, 7477, 7489, 8389, 8800, 10407, 10512, 12035, 13015, 14634, 14941, 16339, 16367, 16554, 26533, 28153, 29081, 30222, 32391, 36371, 37323, 39251, 43935, 45052, 45773, 47239, 49415, 50445, 52637, 56391, 64400, 84059, 85434, 132909, 163192, 186251, 198122, 199127, 200363, 205885, 207555, 220532, 222399, 264459, 269433, 274141, 309331, 317435, 359692, 371488, 377268, 383323, 422243, 433420, 585714, 616479 As I'm a machine down for my own project, I'm bowing out of this 15k/RPS backfilling task for the moment, but may rejoin later. Good luck all!
