    Growing out of my recent edit to the anafunctor article, I've created a new article on cliques.

    Thanks for creating this, Sridhar. I've added an applications section, with an application to monoidal strictification (which should entail some more branching).

    Perhaps we should have a reference to the classical idea of clique from graph theory as well. The Wikipedia article is here:

    I had a stab at making such a reference at clique (the section on Etymology) -- please correct any mistakes.

    That looks a good start. I am not expert but did use them in some work some time ago.

    I have added to the very beginning of clique the concise half-line definition:

    A clique is a functor out of a (-2)-truncated groupoid.

    I added the other consise half-line definition: an anafunctor out of the trivial category.
