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.

Examples

			The sequences a(n)=A072756(n) and b(n)=A104463(n) are jointly defined:
a(n) = least positive integer not a(k) + Floor(a(k)/2) for k<n. Thus
a(0)=0, b(0)=0, a(1)=1, b(1)=1, a(2)=2, b(2)=3, a(3)=4, b(4)=6,...

Formula

A104463(n)=s(n)+Floor(s(n)/2), where s(n)=A072756(n).
