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.

A370865 Numbers m such that c(0) > c(1) <= c(2), where c(k) = number of k's in the ternary representation of m.
