Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

n is in the sequence if and only if it does not rank among the top n positive integers in centrality (cf. A080997 for fuller explanation of this concept).
