A332416 - cp's OEIS frontend

A332416 Positive integers r such that B(1,r) = B(2,r - 1) = ... = B(r,1) = 0, where B denotes the function mapping every pair of positive integers (m,n) into 1 if m * 2^(n + 2) + 1 is a prime number dividing F(n), where F(n) denotes the n-th Fermat number (i.e., F(n) = A000215(n)); and into 0 otherwise.
