![]() " listen" produces a midi file so that you can listen to the sequence.Some noteworthy plots are the Fibonacci numbers A000045, the partition numbers A000041, the Euler phi-function A000010, etc. The first is a pin plot of the first 200 terms (less if fewer terms are available), the second is a linear or log scatter-plot of all available terms, using terms from the b-file if there is one. " graph" produces two plots of the sequence.For an example, see Pascal's triangle, A007318. " table": If the sequence is formed by reading a triangle across rows (or by reading a table by antidiagonals), this button produces three different two-dimensional views of the sequence." refs" shows all the sequences which reference this one." list" produces a numbered list of the terms, plus a bracketed list suitable for importing into other programs such as Maple, Mathemtica, PARI, etc.The sequence pages have little buttons at the top marked " list", " graph", " refs", " listen", " history", " text", " internal format", and sometimes " table" and " edit".See also the hints file for further useful information.

This is the place to find out! (Answer: click here.) The third Supplement to the 1973 Handbook (which supersedes the first two supplements) is available here: Media:Supp3.txt Description of OEIS entries (or, What is the Next Term?) Plouffe's Encyclopedia of Integer Sequences (1995)Ĭontain much useful information about analyzing an unknown sequence and many other topics. Sloane's Handbook of Integer Sequences (1973) Introductory chapters from the 19 books Supplement 3 to 1973 book You might also like to see the list of papers that have acknowledged help from the database and some comments from readers.Also worth visiting are the pages dealing with Puzzle sequences, Classic sequences and Hot sequences.It is like a dictionary or fingerprint file for number sequences. In a way the OEIS can be regarded as an index to all of science. It is also interesting to browse the Index to the OEIS to see the variety of topics that are covered.This can be set to look at the most interesting sequences, recent additions, or sequences needing more terms. ![]()
