is one of the three Abelian
groups of group order 8 (the other two being non-Abelian).
Examples include the modulo multiplication
groups
,
,
, and
(and no others).
The elements
of this group satisfy
,
where 1 is the identity element, and four of
the elements satisfy
.
The cycle graph is shown above.
Its multiplication table is illustrated above.
Since the group is Abelian, each element is in its own conjugacy class.
The subgroups are ,
,
,
,
,
,
,
and
,
A, B, C, D, E, F,
.
Since the group is Abelian, all of these are normal.
