OEIS Sequences

First term of balanced prime quartets: p(m+1)-p(m) = p(m+2)-p(m+1) = p(m+3)-p(m+2). A54800

Initial prime in set of 4 consecutive primes with common difference 6. A33451

Primes p such that p, p+6, p+12, p+18 are all primes. A23271

Numbers k such that the k-th run-length A110969(k) of the sequence of non-prime-powers (A024619) is different from all prior run-lengths. A373670
