This mathematical article is based on four recent articles (2015) by the same author, published in the same journal. The journal is not a reliable source, as it has not mathematics in its topic, and is not reviewed by Zentralblatt MATH nor by MathSciNet. A Scholar Google search shows that the title of the article is a neologism that appear only in these four articles, and that these articles are not cited by other authors. Thus the topic is non-notable WP:OR. D.Lazard (talk) 09:14, 22 January 2017 (UTC)[reply]

Keep – Searching the term gives these three links: [1]; [2]; [3]; from an unrelated website. There is also this, this, and a .edu site here, here and here. The sequence also appears in the OEIS and it cannot be OR because the article is referenced. How do you define notability of a mathematical concept? Also, why did you put a COI tag on the page?

Comment – There is a paper in the IJST, which is peer reviewed (here), so there is fact a reliable source in the article. Laurdecl ^talk 10:32, 22 January 2017 (UTC)[reply]
