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.

A174674 Sequence A154695 adjusted to leading one:t(n,m)=A154695(n,m)-A154695(n,0)+1.
