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.

A017010 a(n) = (7*n+2)^6.

From Wesley Ivan Hurt, Apr 22 2016: (Start)
G.f.: (64 + 530993*x + 13058473*x^2 + 41753398*x^3 + 26472118*x^4 + 2876609*x^5 + 15625*x^6)/(1 - x)^7.
a(n) = 7*a(n-1)-21*a(n-2)+35*a(n-3)-35*a(n-4)+21*a(n-5)-7*a(n-6)+a(n-7).
a(n) = A001014(A017005(n)). (End)
E.g.f.: (64 + 531377*x + 7857199*x^2 + 16549750*x^3 + 9808085*x^4 + 1966419*x^5 + 117649*x^6)*exp(x). - Ilya Gutkovskiy, Apr 23 2016
