I made a longish list of prime triple patterns or 3tuples already in the database.
Some entries from The Online Encyclopedia of Integer Sequences A022004 Initial members of prime triples (p, p+2, p+6). 5,11,17,41,101,107 and so on A046134 p, p+2 and p+8 are primes. 3, 5, 11, 29, 59, 71, 101, 149, 191, 269 and so on A046135 Primes p such that p+2 and p+12 are primes. 5, 11, 17, 29, 41, 59, 71, 101, 137, 179, 227, 239, 269, 281, 347, 419 and so on A046136 Primes p such that p, p+4 and p+10 are primes. 3, 7, 13, 19, 37, 43, 79, 97, 103, 127, 163, 223, 229, 307, 349, 379, 439 and so on A046137 Primes p such that p+4 and p+12 are also prime. 7, 19, 67, 97, 127, 229, 397, 487, 739, 757, 907, 1009 and so on A046138 p, p+6 and p+8 are primes. 5, 11, 23, 53, 101, 131, 173, 191, 233, 263, 563, 593, 653 and so on A046139 p, p+6 and p+10 are primes. A046141 p, p+8 and p+12 are primes. I have tried to contribute a few prime triples to OEIS but was told that these sequences are 'not of general interest'. Maybe someone else would like to try. Note the pattern Primes p such that p, p+2 and p+14 is not in the OEIS database. It starts with 3,5,17,29,59,137,149,179,197,227,269,419,599,617,659,809,1019,1049,1277,1289,1607,1787,1997 and so on. Any takers? Regards, Matt

triple prime log
Again,
If someone wants to put a few prime triples in OEIS, you can try. I also tried (0, 2, 20) but that one was rejected too. "not of general interest". But I have made donations to OEIS and I received a holiday card from Neil Sloan himself, so the wheel may be greased. Regards, Matt

a short calculation
Now I have a calculation to share. It is a 3tuple. Pattern is (0,2,18). I 'dialed it in' to fit on one piece of paper, and printed one. I used Maple computer algebra system and computer language.
I bet you can't calculate more Look Matt Eddited to add  Have you ever dialed in a radio station? It is fun. Some of us know the joy of finding special numbers. You, dear reader, and I are special. We are elite. Some people can't even read. Best of luck. M Last fiddled with by MattcAnderson on 20211128 at 06:29 Reason: got bored

Triple prime search with pattern (0, 2, 20)
Where 20 is an arbitrary parameter :)
This is what I was told by an OEIS.org referee. *sigh* Hi again all, Here are more triple prime search data. It is for your enjoyment. I put it on this public forum so that it may be shared. These are prime numbers p such that p, p+2, and p+20 are all prime numbers. So, this is a pattern of (0, 2, 20). And these are the smallest such positive prime numbers. And all prime numbers are positive integers. Again, someone else can try to put this in OEIS. Because, hey mankind needs to know this. (But maybe, 'not of general interest') Regards, Matt

You could use PFGW with this script:
Code:
ABC2 $a & $a+2 & $a+20 a: from 1 to 20000 step 2 The log file "pfgwprime.log" will contain all pairs in this form: Code:
3 3+2 3+20  Complete Set

Just to make the list a bit more exclusive, I told PariGP to look for primes p such that p + 2 and p + 18 were the next two consecutive primes. With the small limit I chose, it would have taken more time figuring out time saving refinements than it took to write and run a mindless script.
Code:
k=0;forprime(p=3,35000,q=nextprime(p+1);r=nextprime(q+1);if(qp==2&&rq==16,k++;print(k" "p" "q" "r))) 1 1931 1933 1949 2 2111 2113 2129 3 2591 2593 2609 4 2801 2803 2819 5 3119 3121 3137 6 3371 3373 3389 7 3389 3391 3407 8 5021 5023 5039 9 5279 5281 5297 10 5879 5881 5897 11 6761 6763 6779 12 7331 7333 7349 13 9011 9013 9029 14 9239 9241 9257 15 10271 10273 10289 16 11351 11353 11369 17 11699 11701 11717 18 16631 16633 16649 19 17579 17581 17597 20 17789 17791 17807 21 18059 18061 18077 22 18311 18313 18329 23 18521 18523 18539 24 19139 19141 19157 25 20231 20233 20249 26 20771 20773 20789 27 22091 22093 22109 28 22619 22621 22637 29 24179 24181 24197 30 26861 26863 26879 31 27281 27283 27299 32 30011 30013 30029 33 31121 31123 31139 34 32141 32143 32159 35 32939 32941 32957 36 33809 33811 33827 37 34649 34651 34667 ?
