Sep. 8th, 2022 03:02 pmBy a graphic we will mean any finite category each of whose endomorphism monoids satisfies the identity xyx = xy ; in particular, a graphic monoid is a graphic category with one object.
By an application of a graphic category we will mean any right action of it on finite sets (i.e. any contravariant finite-set- valued functor on it).

I think social networking satisfies this requirement, e.g. Make Use Make = Make Use (a user to Make a new user).
