Small primes[size=+1]Here you can post small primes (no entry for the Top5000 list).[/size]
[b]Notes:[/b] 1. For some primes (about <50) a comma separated list within your post is ok. 2. For more primes (especially for more than one k-value) an attachment in ASCII-format is better (one k-value per line with all primes for this k). 3. Please try to check for twins, too (not necessary but helpful). 4. Give the search ranges for n-values. Thanks. |

As a first entry a PM from Mathew:
[code] kar_bon, I have done k=221409 for R2 to n=45000 this should clean up some. 1, 3, 4, 11, 12, 15, 23, 29, 39, 73, 75, 164, 201, 299, 327, 397, 437, 551, 661, 723, 1103, 1179, 1227, 1391, 1589, 2092, 2348, 2413, 2972, 5429, 5476, 5917, 7497, 8108, 11333, 13613, 14879, 20053, 21172, 21644, 35929, 36452, 38409, 41409 Is there anything else you need?
