This makes it the largest database of its kind. Each entry contains the leading terms of the sequence, [[keyword]]s, mathematical motivations, literature links. It also includes the option to generate a [[graph]] or play a [[Computer music|musical]] representation of the sequence. The database can be searched by keyword and by subsequence. For instance, it is possible to search for all sequences with both 15 and 118. [[Category:Mathematics]] [[Category:American science websites]] {{math-stub}}
