COMMENTS
| Minimal difference is 6 (for 3-tuplet). Repeating 6 means successive 3-tuplets.

FORMULA
| Partition primes in triples starting with 7: {7, 11, 13}, {17, 19, 23}, {29, 31, 37}, {41, 43, 47}, {53, 59, 61}, {67, 71, 73}, {79, 83, 89}, {97, 101, 103}, {107, 109, 113}. Sequence gives differences between lesser and larger primes in triples.
