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.

A264934 Decimal expansion of number with continued fraction expansion 0, 1, 11, 111, 1111, 11111 ... (the repunits).
