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.

A175135 Numbers k such that there exist permutations p, q of some size m such that k = f_m(f_{m-1}(...f_1(1)...)), where f_i(x) = p_i*x + q_i.
