This group is defined in the following equivalent ways:
- It is the cyclic group of order .
- It is the direct product of the cyclic group of order five and the cyclic group of order two.
This finite group has order 10 and has ID 2 among the groups of order 10 in GAP's SmallGroup library. For context, there are groups of order 10. It can thus be defined using GAP's SmallGroup function as:
For instance, we can use the following assignment in GAP to create the group and name it :
gap> G := SmallGroup(10,2);
Conversely, to check whether a given group is in fact the group we want, we can use GAP's IdGroup function:
IdGroup(G) = [10,2]
or just do:
to have GAP output the group ID, that we can then compare to what we want.
The group can be defined using GAP's CyclicGroup function:
