Pictures from the OEIS

The (Free) OEIS Store

The On-Line Encyclopedia of Integer Sequences (or OEIS) is a huge collection of number sequences, maintained by The OEIS Foundation Many of these sequences have spectacular illustrations, some of which are shown here.They would look pretty good on T-shirts, tote bags, banners, posters, coffee cups, etc.

For about ten seconds we considered charging a fee for downloading these pictures,

but remembering how much we hate journals that hide articles behind paywalls, we decided against it.

However, if you make use of any of these pictures, we hope you will consider making a donation to The OEIS Foundation.
