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.

A024571 a(n) = [ sum of 1/{k*r} ] for k = 1,2,...,n, where r = (1 + sqrt(5))/2 and {x} := x - [ x ].
