This is a front-end for the Online Encyclopedia of Integer Sequences, made by Christian Perfect. The idea is to provide OEIS entries in non-ancient HTML, and then to think about how they're presented visually. The source code is on GitHub.

Formula

E.g.f.: exp(exp(x*y/(1-x))-1). a(n, k) = n!/k! * binomial(n-1, k-1) * bell(k) = |A008297(n, k)| * A000110(k).
