This group is defined as the external direct product of special linear group:SL(2,3) (the special linear group of degree two over field:F3, the field of three elements) and cyclic group:Z2 (the cyclic group of two elements). It is denoted or .

This finite group has order 48 and has ID 32 among the groups of order 48 in GAP's SmallGroup library. For context, there are groups of order 48. 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(48,32);
Conversely, to check whether a given group is in fact the group we want, we can use GAP's IdGroup function:
IdGroup(G) = [48,32]
or just do:
to have GAP output the group ID, that we can then compare to what we want.
