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.

A323478 a(1)=1; thereafter, a(n) = string appended to (n-1)-st generation of A306211 to get the n-th generation.

The concatenation of these terms is the sequence A306211 itself.
The concatenation A323477(n-1) followed by a(n) is A323477(n). For example, if n=6, 11221221.22121 = 1122122122121.
The strings a(n) are converging to A323826, the RUNS transform of A306211.
