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.

A137595 Integers k such that the run lengths of identical digits in their binary expansion are palindromic after the rightmost bit is duplicated.
