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.

A165417 a(0) = a(1) = 1. For n >=2, a(n) = sum a(k), where k is over the distinct values of the substrings in binary n, and where 0 <= k < n.
