• A highly selective Index to theOn-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 alwayssearch the database for a particular word or phrase.
• Entries with a double colon (::) are from the index to the 1995 bookThe 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 Most of these entries are now out of date and need to be revised.
