| Oct 23, 2009 at 4:55 | comment | added | Theo Johnson-Freyd | @Tom: I think "concretized" is a great word. The "concrete category" should mean "category equipped with a faithful functor to SET", rather than the existence of such a thing. | |

| Oct 23, 2009 at 2:45 | comment | added | Tom Leinster | Can you define "concretized"? It's not a common term in category theory. Sometimes people call a category concrete if there exists (or if it comes equipped with) a faithful functor to the category of sets. But usage varies. | |
