On-Line Encyclopedia of Integer Sequences

The On-Line Encyclopedia of Integer Sequences (OEIS) is an online database of integer sequences, created by Neil Sloane in 1964 and later transferred to the OEIS Foundation in 2009. It contains over 390,000 sequences and is widely cited by professional and amateur mathematicians. Each entry includes terms, keywords, mathematical motivations, and literature links, with options to generate graphs or musical representations. The database is searchable by various fields and employs an advanced 'SuperSeeker' function to identify related sequences.

Note

of course this exists.

a few fun sequences to explore the fly away, the forest fire and so on and so on plus one and so one plus two.

the automated graphs and variety of metadata recorded for each sequence are all worth reading through when you find a sequence to your liking. a well done repository!
