COMMENTS

This subsequence of A125830 and of A162174 gives primes of level (1,15): 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(16042282)-prime(16042281)=prime(16042281)-prime(16042281-15),

=prime(16042281)-prime(16042266); 295902247-295902073=295902073-295901899=174=6*29;

since prime(16042281) has level 1 in A117563, prime(16042281)=295902073 has level(1,15).
