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.

Let x = A187922(n) and r = A005132(x-1) - x, by definition of A187922: r > 0 and r occurs earlier in Recamán's sequence: a(n) = A057167(r) or r = A005132(a(n)), hence A005132(x) <> r but A005132(x) = A005132(x-1) - x.

Examples

			n = 5: x = A187922(5) = 19, r = A005132(19-1) - 19 = 43 - 19 = 24 = A005132(15): a(5) = 15.
