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.

Comments

The word "above" in the definition is somewhat ambiguous. More precisely, this is the list of n such that A065188(n) >= n.
If one looks at the graph of A065188, the points appear to lie roughly on two lines, of slopes phi (the golden ratio) and 1/phi. The points in the present sequence appear to fall on the line of slope phi. That is, it is appears that A065188(a(n))/a(n) -> phi as n -> oo.
