OEIS Sequences

Primes from merging of 5 successive digits in decimal expansion of π. A104825

Larger of two consecutive prime numbers, p1 and p2 = p1 + d, such that p1·p2·d - d is the average of twin primes. A153379

Primes of the form 2n²+14n+5. A154577

Wiener index of a benzenoid consisting of a double-step spiral chain of n hexagons (n>=2, s=21; see the Gutman et al. reference). A193397

a(n) = a(1) + a(2) + ... + a(n-1) + a(m) for n >= 4, where m = n - 1 - 2^p and p is the unique integer such that 2^p < n - 1 <= 2^p+1, starting with a(1) = a(2) = a(3) = 1. A49934

Reduced binary string self-substitutions: a(n) is obtained by substituting n for each 1-bit in the binary expansion of n, then dividing by n. A65160
