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.

A226244(n) = A005185(a(n)).

Examples

			a(8) = 15 because the first 15 terms of Hofstadter's Q-sequence are 1,1,2,3,3,4,5,5,6,6,6,8,8,8,10, and the 8th successive maximum is 10, which appears for the first time at position 15
