OEIS Sequences

Indices of records of minimal distance between successive Riemann ζ zeros. A326502

Numbers m such that d(m) < d(k) for all k < m, where d is the normalized δ defined as d(m) = (z(m+1) - z(m))*(log(z(m)/(2*π))/(2*π)) where z(k) is the imaginary part of the k-th Riemann ζ zero. A328656

a(n) = a(1) + a(2) + ... + a(n-1) - a(m) for n >= 4, where m = 2·n - 2 - 2^p+1 and p is the unique integer such that 2^p < n - 1 <= 2^p+1, starting with a(1) = 1 and a(2) = a(3) = 3. A49927
