 OFFSET 1,1 COMMENTS 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). Subsequence of A125830 and of A162174. LINKS Remi Eismann, Table of n, a(n) for n = 1..10000 EXAMPLE Prime(115) - prime(114) = prime(114) - prime(114-3) = 631 - 619 = 619 - 607. CROSSREFS Cf. A117078, A117563, A117876, A118464.
