OEIS Sequences

Initial term in sequence of four consecutive primes whose consecutive differences have d-pattern = [6, 4, 6]; short d-string notation for pattern = [646]. A78856

Smaller member p of a pair (p,p+6) of consecutive primes in different centuries. A160370

Number of divisors of n! which are also differences between consecutive divisors of n! (ordered by size). A60742

Numerator of ∑_k=0..[n/2] 1/binomial(n,k). A100560

Primes p such that all the digits needed to write the consecutive Primes from 2 to p fill exactly a square (no holes, no overlaps). A158024

a(n) = n·A340339(n)+b, where b = 1 if n is even or 2 if n is odd. A340340

G.f. satisfies A(x) = exp( ∑_k>=1 (A(x^k) + A(i·x^k) + A(-x^k) + A(i³*x^k))/4·x^k/k ), where i = sqrt(-1). A363405
