cp's OEIS Frontend

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

Recurrence: (n+10)*(n+18)*(n+24)*(n+28)*(n+30)*a(n) = (6*n^5 + 535*n^4 + 17752*n^3 + 265085*n^2 + 1658520*n + 2755377)*a(n-1) + (n-1)*(125*n^4 + 7472*n^3 + 149299*n^2 + 1090536*n + 1857231)*a(n-2) - 2*(n-2)*(n-1)*(270*n^3 + 11843*n^2 + 154023*n + 546120)*a(n-3) - (n-3)*(n-2)*(n-1)*(3319*n^2 + 74458*n + 331317)*a(n-4) + 3*(n-4)*(n-3)*(n-2)*(n-1)*(2578*n + 28701)*a(n-5) + 10395*(n-5)*(n-4)*(n-3)*(n-2)*(n-1)*a(n-6).
a(n) ~ 40186125/1024 * 11^(n+55/2)/(Pi^(5/2)*n^(55/2)).
Conjecture: a(n) ~ k^n/Pi^(k/2)*(k/n)^(k*(k-1)/4) * prod(j=1,k,Gamma(j/2)).
