didn't find a place for recreational sequences - these don't exactly fit to puzzle, classic or hot ones. Could you either tell me if there's one, or if not, point me to create a new page if there's demand for that? The sequence I'm thinking about is greediv (greedy division). The idea is that you go backwards summing the previous members until the sum is divisible by wanted n. Then the sum is divided by n and that becomes the new last member. Greediv2 was fully solved in <a href="http://oeis.org/A003558">A003558</a>, but the higher n's are more elusive. <a href="/wiki/User:Juhani_Heino" title="User:Juhani Heino">Juhani Heino</a> 09:53, 9 July 2017 (UTC) </p> <h2><span class="mw-headline" id="Wikidata_property_P829">Wikidata property P829</span></h2> <p>P829 is OEIS ID, a property used on "items" (roughly, Wikimedia pages tracked by Wikidata) with a corresponding OEIS page: <a rel="nofollow" class="external text" href="https://www.wikidata.org/wiki/Property:P829">P829 on Wikidata</a>.
