Summary: My God!
Review: Since combinatorics is my major, this book fulfills my dream. It contains over 5000 sequences, from famous Fibonacci to notorious 1,3,6,11,17,25,... (Perfect ruler,general term still unknown ), to nonsense 1,11,21,1211,111221,..(every term describe the former term). Nearly every important integer sequence in mathematics get a line here, with references. This is a dream book for combinatorics specialists, a must for high-school teachers while doing some short essays with gifted students, a fun book for mathematics fans, especially those like mathematical games.

Summary: Searching for the book vs. the disk?
Review: The Encyclopedia of Integer Sequences is available in three formats. Sellers often incorrectly match the ISBN to the format. It may be helpful to know the ISBN, rather than to rely on the results of a search by Title/Author. Hardcover Book: ISBN 0125586302
Macintosh Disk: ISBN 0125586310
MSDOS/IBM Disk: ISBN 0125586329 Also, use the price as a clue to which item you will be receiving - the book sells for $70+, the disk for under $20.

Summary: This is a data disk, not the book
Review: This product is not the Encyclopedia of Integer Sequences as it is portrayed here on Amazon; it is instead an almost useless data disk. The integer sequences are there all right, in lexicograhic order; but they are completely unidentified (except for a code number keyed to the book)! In other words, without the book this very expensive diskette is useless. Basically I consider this to be false advertising. Do not buy it unless you already have the book and want a machine-readable, searchable copy of the sequences.
