A cyclic group is a group that can be generated by one element. An element g generate the group if every element of the group can be obtained by repeated applying the group operation or its inverse to g.An Abelian group is a group for which the elements commute (i.e., for all elements and. ). Abelian groups therefore correspond to groups with symmetric multiplication tables. All cyclic groups are Abelian, but an Abelian group is not necessarily cyclic. All subgroups of an Abelian group are normal.
to show that (z,+) is an abelian group we need following properties
1) closure property
2) associative property
3) existence of identity
4) existence of inverse
5) commutative property
The reason why (Z, *) is not a group is that most of the elements do not have inverses. Furthermore, addition is commutative, so (Z, +) is an abelian group. The order of (Z, +) is infinite. The next set is the set of remainders modulo a positive integer n (Zn), i.e. {0, 1, 2, ..., n-1}.
