What a wonderful resource. n stays small, but that is the nature of (tractable) combinatorics.

great for checking your thinking and small tests

What is this?

It appears to be a server which generates combinatorial objects and provides useful descriptions of the same.

Thanks, I gathered that. What kinds of problems does this tool solve?

It solves the problem of being able to teach you about some interesting mathematical objects and algorithms for enumerating them.
