OEIS Sequences

Second members D of two non-consecutive numbers such that the sums of their cubes are equal to centered cube numbers and to at least one other sum of two cubes, i.e., A = B³ + (B+1)³ = C³ + D³ = E³ + F³. A352223

Expansion of e.g.f.: exp(2·x/(1-x)). A52897

a(n) is the smallest number k larger than a(n-1) such that n·d(k)*sopf(k)=σ(k), where d is the number of divisors (A000005) and sopf the sum of prime factors without repetition (A008472). A134382

Square array read by upward antidiagonals, A(n,k) = ∑_j=0..n (n-j)!*C(n,n-j)* C(n-1,n-j)*k^j, for n>=0 and k>=0. A253286

Place n equally spaced points on each side of a square, and join each of these points by a chord to the 3·n new points on the other three sides: sequence gives number of regions in the resulting planar graph. A367278
