A group having a cyclic normal subgroup such that the quotient group by this normal subgroup is also cyclic (cf. Cyclic group). Every finite group of square-free order (i.e. the order is not divisible by the square of a natural number) is metacyclic. Polycyclic groups (cf. Polycyclic group) are a generalization of metacyclic groups.
Comments
Sometimes, the term metacyclic is reserved for the more special class of groups whose derived group and derived quotient group are both cyclic.
