Removed from DOAJ (2017-06-20). DOAJ's stated reason: Journal not adhering to Best practice. A removal from the Directory of Open Access Journals is a quality/transparency signal — it can mean the journal became inactive or failed DOAJ's re-review criteria. This is not proof of predatory practice, but verify the journal's current status and policies before submitting. Check on DOAJ ↗

Aims & Scope

The journal is devoted to papers dealing with integer sequences and closely related topics. The Journal's main topic is integer sequences. Because of the volume of submissions, we are restricting our attention to papers that deal explicitly with this topic. Please be sure to justify that the subject of your article is relevant. For example, you should cite relevant sequences from the OEIS. If you have new sequences, please submit them to the OEIS before submission and cite the relevant A-numbers. The kinds of papers we seek are typically as follows: A new integer sequence and its nontrivial interesting properties New combinatorial interpretations of existing sequences New, mathematically-interesting connections between known sequences An unexpected appearance of a known sequence Proofs or refutations of conjectures on known sequences New techniques or algorithms to compute additional terms of hard-to-compute sequences

Frequently asked questions about Journal of Integer Sequences

Is Journal of Integer Sequences a predatory journal?

Journal of Integer Sequences was withdrawn from the Directory of Open Access Journals (DOAJ) — DOAJ's stated reason: "Journal not adhering to Best practice" (2017-06-20). Withdrawal is not a predatory verdict, but it is a material editorial signal; it remains indexed in Web of Science, Scopus. Verify the journal's current status on DOAJ and its official site before submitting.

What is the impact factor of Journal of Integer Sequences?

Journal of Integer Sequences is indexed in the Web of Science Core Collection, so Clarivate publishes an official Journal Impact Factor for it (since the 2023 Journal Citation Reports, every Core Collection journal — including Arts & Humanities and Emerging Sources titles — receives one). PubScope links to Clarivate's official source rather than reprinting the number, which can be out of date.

Is Journal of Integer Sequences indexed in Scopus and Web of Science?

Journal of Integer Sequences is indexed in Web of Science, Scopus.
