The Number of Group Homomorphisms from Dm into Dn.

In this article, the author reflects on the enumeration of the homomorphisms between two specified cyclic groups. He discusses an example of number of group homomorphism from dihedral group Dm into dihedral group Dn and presents a theorem related to homomorphism. He further states that one can count the number of group homomorphisms between any two dihedral groups with the help of elementary group theory only.
