**Robert**, congrats on locating first dodecaproths.

But note that there are 9 not 14 distinct ones because you counted some twice (once to the right, once to the left) like for example:

44 9604223498415 1 4 5

45 9604223498415 4 1 5

I verified that members of all 9 are primes, here is the output of my Pari script:

Code:

7946515823715 44 is OctoProth! ... and DodecaProth!!
9604223498415 44 is OctoProth! ... and DodecaProth!!
10872870991605 44 is OctoProth! ... and DodecaProth!!
45960089776965 47 is OctoProth! ... and DodecaProth!!
69283546229205 47 is OctoProth! ... and DodecaProth!!
19000157002995 49 is OctoProth! ... and DodecaProth!!
374180855930805 49 is OctoProth! ... and DodecaProth!!
502414540060965 49 is OctoProth! ... and DodecaProth!!
555428994253665 49 is OctoProth! ... and DodecaProth!!

where I define (k,n) to be DodecaProth if both (k,n) and (k,n+1) are OctoProths. BTW, I checked the table provided by Greenbank but found no DodecaProths for n=50.
