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.

A355847 Irregular table read by rows, in which the rows list integers formed in the process in A180301, but generalized to other starting integers. A row ends when reaching a term in A180301.
