# Deleted sequences

### From OeisWiki

- Sequences are occasionally removed from the OEIS and their A-numbers recycled.
- Remember that if you delete a sequence, you must also delete (or update) all references to it in other entries—first do a search for the A-number in oeis.org, then here in the OEIS wiki (in case there are references to it in the wiki pages).
- If the deleted sequence had a b-file, that must be deleted also, or it will cause problems when the A-number is recycled. To delete a b-file, contact David Applegate, Russ Cox, Charles R Greathouse IV, or N. J. A. Sloane.
- Sequences that have been in the OEIS for a long time (even if they already have keyword "dead") should not be deleted. If they are incorrect or duplicates they can be given the keyword "dead".

## Reasons for deletion

There are several reasons why a sequence may be deleted from the OEIS. Typically, this happens if the sequence is:

- a duplicate of a sequence already in the OEIS,
- an erroneous version of a sequence already in the OEIS,
- ill-defined (e.g. eventually some term has multiple or ambiguous values, or the sequence is time-dependent),
- withdrawn by the author,
- does not contain enough terms (usually we need at least four terms),
- too artificial or contrived,
- not of general interest (NOGI),
- contains unacceptable language,
- a new submission which has been on the
**Sequences awaiting review**(**Proposed drafts**or**Pending changes**) list for over three months. (This usually happens when the author does not respond to the editors' questions.)

## Some advice

To ensure that your sequence is not deleted:

- Be very careful when calculating the sequence;
- Give a precise definition;
- Check that the sequence (even without the initial terms) is not already in the OEIS;
- Write in correct English;
- Include a comment saying why the sequence is interesting;
- Give an example;
- Say how you computed the sequence;
- Give a computer program.

## List of deleted sequences

This is a list of sequences which have been deleted, starting from the most recent.

- "rifo" means "retired in favor of" (in other words, "the latter sequence is preferable").
- "NOGI" means "Rejected because not of general interest".

One can use either a simple dash or hyphen (-) or an `—` (—) before a signature.
