Finite Group Z2
The unique group of Order 2. 
is both Abelian andCyclic. Examples include the Point Groups 
, 
, and 
, the integers modulo 2under addition, and the Modulo Multiplication Groups 
, 
, and 
. Theelements 
satisfy 
, where 1 is the Identity Element. The Cycle Graph is shown above, and theMultiplication Table is given below.

The Conjugacy Classes are 
and 
. The irreducible representation for the group is
