Neil Sloane started collecting integer sequences as a graduate student in to support his work in combinatorics. For latest updates on this blog and other mathematical miscellany follow me on twitter and Facebook.

If we start at the beginning of the sequence, then, as illustrated below, the length of the runs recreates the original sequence. Greek letters are usually represented by their sloand names, e.

In fact, one of the great strengths of the OEIS is that it unites professionals and amateurs.

On-Line Encyclopedia of Integer Sequences. Marks from the year-old Ishango bone from the Congo. Neil has lost none of his excitement about sequences. For example, inreger prime numbers — the numbers that can only be divided by themselves and 1 — form a sequence: Some people collect stamps, some collect fossils but Neil has always collected sequences.

You extract sieve out all the appearances of the prime numbers in the decimal expansion of integee.

In other words, to be inventive in this medium, one must have mastery of only two things, numbers and ideas. Retrieved 1 October As a spin-off from the database work, Sloane handbok the Journal of Integer Sequences in So if you put in 0, 1, 1, swquences, 3, 5 you will get the Fibonacci sequence, as well as more than others that also include these numbers.

Retrieved from ” https: Besides integer sequences, the OEIS also catalogs sequences of fractionsthe digits of transcendental numberscomplex numbers and sllane on by transforming them into integer sequences. This sequence spurred progress on finding more terms of A If you have your own favourite sequences from the OEIS, please list them in the comments section with the reasons why.

You can search for sequences by inputting numbers. Prime numbers and Fibonacci numbers are well known throughout general culture.

Digit groups are not separated by commas, periods, or spaces. These books were well received and, especially after the second publication, mathematicians supplied Sloane with a steady flow of new sequences. He sequemces only interested in integer sequences, which are those made up of whole numbers and negative numbers and zero.

A Handbook of Integer Sequences. Threads collapsed expanded unthreaded. He mentioned a sequence submitted by Jan Ritsema Van Eck in And when I come across a sequence I put it in the database.

Retrieved 25 December The collection became unmanageable in book form, and when the database had sequenfes 16, entries Sloane decided to go online—first as an e-mail service Augustand soon after as a web site But if the number sequecnes has appeared previously in the sequence, then you count the number of terms since the last appearance of kand that number is the following term.

Mathematicians and scientists use the OEIS all the time. There are 4 solutions for hanbdook, but no solutions for 14, hence a 14 of A is 0—there are no solutions.

Aor continued fraction expansions here 3, 7, 15, 1,1, 1, 1, 2, 1, 3, 1, 14, 2, 1, 1, 2, 2, 2, 2, 1, 84, 2, 1, 1, A lists the first term given in sequence Integfr nbut it needs to be updated from time to time because of changing opinions on offsets. It is also a badge of honour to get a sequence accepted — although Neil and the administrators tend to be very generous in their selection criteria.
