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.

5207*84+1=437389 is the first term in the sequence.
This is not a subsequence of A059236.
437389 = A059236(908), 510287 = A059236(1046), 541529 = A059236(1106).
3228341, 3624073 and 8091679 belong to this sequence but not to A059236. - Joerg Arndt and Arkadiusz Wesolowski, Jun 26 2011
