Template:Cyclic group of prime order

From Groupprops

Definition

This group, denoted {{{3}}} is defined as the cyclic group of order {{{2}}}. Equivalently, it is the additive group of the [[field:F{{{1}}}|field of {{{4}}} elements]].

Note that {{{1}}} is prime, and thus by the classification of groups of prime order, this is the only [[groups of order {{{1}}}|group of order {{{1}}}]].

GAP implementation

Group ID

This finite group has [[groups of order {{{1}}}|order {{{1}}}]] and has ID 1 among the groups of order {{{1}}} in GAP's SmallGroup library. For context, there are groups of order {{{1}}}. It can thus be defined using GAP's SmallGroup function as:

SmallGroup({{{1}}},1)

For instance, we can use the following assignment in GAP to create the group and name it :

gap> G := SmallGroup({{{1}}},1);

Conversely, to check whether a given group is in fact the group we want, we can use GAP's IdGroup function:

IdGroup(G) = [{{{1}}},1]

or just do:

IdGroup(G)

to have GAP output the group ID, that we can then compare to what we want.


Other descriptions

The group can be constructed using GAP's CyclicGroup function:

CyclicGroup({{{1}}})
