This group can be defined in two equivale ways:
- It is the Ree group with parameter value 3, i.e., the group . Equivalently, it is the Ree group where . It is the only Ree group that is not simple. The Ree groups , , are all simple.
- It is the projective semilinear group of degree two over field:F8, i.e., it is the group .

This finite group has order 1512 and has ID 779 among the groups of order 1512 in GAP's SmallGroup library. For context, there are 889 groups of order 1512. 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(1512,779);
Conversely, to check whether a given group is in fact the group we want, we can use GAP's IdGroup function:
IdGroup(G) = [1512,779]
or just do:
to have GAP output the group ID, that we can then compare to what we want.
