[Math] How to cite a sequence from The On-Line Encyclopedia of Integer Sequences (OEIS)

citationsjournalsoeissoft-question

In my paper I want to provide a reference for a sequence (in this case – A001970) from The On-Line Encyclopedia of Integer Sequences (OEIS).

However, I couldn't find an official bib entry for it (there is an unofficial OEIS2BibTeX). Even the respective FAQ/Wiki entry is a bit vague on the issue, providing only a suggestion:

A text reference might say:

The On-Line Encyclopedia of Integer Sequences, published electronically at http://oeis.org, 2010, Sequence A000108

or, if it is clear who "discovered" the sequence, something like

J. H. Conway, Sequence A007970 in The On-Line Encyclopedia of Integer Sequences (2010), published electronically at http://oeis.org.

Moreover, in most of papers I saw people add N. [J. A.] Sloane but drop the year, e.g.:

N. J. A. Sloane, The On-Line Encyclopedia of Integer Sequences, Sequence A000009.

So, is there a "good practice" for citing OEIS sequences?

The OEIS website http://oeis.org/wiki/Works_Citing_OEIS#Referencing_the_OEIS provides this info:

If you have found the OEIS useful in your own work, and wish to reference it, the usual citation is

OEIS Foundation Inc. (2019), The On-Line Encyclopedia of Integer Sequences, http://oeis.org.

To reference a particular sequence, the usual citation is

OEIS Foundation Inc. (2019), The On-Line Encyclopedia of Integer Sequences, http://oeis.org/A123456.
