preordered class is a
class equipped with a preorder. When
dealing with a
class C, it is
possible to

- set (considered as a
preordered set) is the
initial object of PreOrd, and the
terminal objects are
precisely the

There are thus...

Every set is a
class and so
every preordered set is a
preordered class. Preorders...
-
particularly in
order theory, an

Discrete categories are the
