Index to OEIS

• A highly selective Index to the On-Line Encyclopedia of Integer Sequences™ (or OEIS®)
• The principal sequences are marked by asterisks (*). See also the list of "core" sequences.
• The goal here is to try to group the principal sequences into categories, to make it easier to locate sequences dealing with a particular topic.
• If you did not find what you were looking for in this Index, you can always search the database for a particular word or phrase.
• Entries with a double colon (::) are from the index to the 1995 book The Encyclopedia of Integer Sequences, by N. J. A. Sloane and Simon Plouffe. Most of these entries are now out of date and need to be revised.
• Please read Index: Instructions For Updating Index to OEIS before making changes to any of the sections of this Index.
