#### Solution Preview

This is only true if we consider isomorphic objects in a category to be the same.

If we have such a category C then define a partial order on the set of objects

O : a <= b iff there is a morphism from a to b.

If a <= b and b <= c, then we can compose the morphisms to ...

#### Solution Summary

Partially-Ordered Sets ( Posets ) and Hom-sets are investigated. The solution is detailed and well presented.
