In this paper, we extend the notions of friendly and solitary
numbers to group theory and define friendly and solitary groups of
type-1 and type-2. We provide many examples of friendly and
solitary groups and study certain properties of the type-2 friends
of cyclic $p$-groups, where $p$ is a prime number.
