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

			This permutation touches only the rationals in the range ]1/2, 3/4[, which for example contains the sixth node = 3/5 of the SB ]0,1[ tree (A007305/A007306) which has an infinite, but periodic binary fractional expansion 0.100110011001... and by this permutation it is changed to 0.1010100110011001... = 53/80, which is located as the 234881023th node in the SB ]0,1[ tree.
