Summary

Relationships between different kinds of homomorphisms.
H = set of Homomorphisms
M = set of Monomorphisms
P = set of ePimorphisms
S = set of iSomorphisms
N = set of eNdomorphisms
A = set of Automorphisms

Notice that:
M ∩ P = S,
S ∩ N = A,
P ∩ N = A,
and M ∩ N \ A contains only infinite homomorphisms.
