Can you elaborate a bit on the last sentence? What exactly are the relations and what is the set?

If you want a description of the monad laws in Haskell terms you can Google and find like 80 expositions on the topic of various depths.

If you want a mathematical exposition. "Category Theory" by Awodey page 265 is a concise description.
