COMMENT
|
This subsequence of A125830 and of A162174 gives primes of level (1,16): 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(48470200)-prime(48470199)=prime(48470199)-prime(48470199-16)
=prime(48470199)-prime(48470183): 950803519-950803363=950803363-950803207=156=6*26,
prime(48470199) has level 1 in A117563, so prime(48470199)=950803363 has level(1,16).
