COMMENTS

This subsequence of A125830 and of A162174 gives primes of level (1,13): If the i-th prime p(i) has level 1 in A117563 and 2 p(i) - p(i+1) = p(i-k), then we say that p(i) has level (1,k).

EXAMPLE

prime(10272256)-prime(10272255)=prime(10272255)-prime(10272255-13),

prime(10272256)-prime(10272255)=prime(10272255)-prime(10272242),

184607153-184606997=184606997-184606841=156=6*26,

prime(10272255) has level 1 in A117563,

prime(10272255)=184606997 has level(1,13).
