Frequently Asked Questions
What is the Gijswijt sequence?
A sequence where each term counts the largest number of times a block of earlier terms repeats just before it.
How slowly does it grow?
Famously slowly. The first 4 does not appear until far along, and a 5 not until an astronomically large position.
How many terms can I list?
Up to two thousand, since each term requires scanning all the terms before it.
Is anything uploaded?
No. The sequence is generated in your browser, so nothing leaves the tab.
Is it free?
Yes. Every tool here is free to use with no sign up.
