OEIS (On-Line Encyclopedia of Integer Sequences)

The OEIS (On-Line Encyclopedia of Integer Sequences) is a comprehensive digital database that catalogs sequences of whole numbers, like patterns or series that appear in mathematics, science, and other fields. It provides detailed descriptions, formulas, references, and related information for each sequence, enabling researchers and enthusiasts to identify, analyze, and understand numerical patterns. Think of it as an extensive, searchable library for integer sequences, helping users recognize familiar sequences and discover new ones, thereby supporting mathematical exploration and discovery.
