The category of finite sets and isomorphisms versus the category with
objects
1,2,...,n,... and the symmetric groups \Sigma_n as morphisms
The category of `modules' over one is equivalent to
The category of `modules' over the other
Is this somewhere in the literature or just folk lore?
Maybe for one n at a time??
thanks
jim
