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.

A059652 a(n) = [[(k^2)*n]-(k*[k*n])], where k = sqrt(3/2) and [] is the floor function.
