The special unitary group $SU\left(n\,q\right)$ is the set of all n x n matrices over the field with $q^2$ elements whose determinant is $1$ and respect a fixed nondegenerate sesquilinear form.

The SpecialUnitaryGroup( n, q ) command returns a permutation group isomorphic to the special unitary group  $SU\left(n\,q\right)$ .

Note that for n = 2 the groups $SU\left(n\,q\right)$ and $SL\left(n\,q\right)$ are isomorphic so the latter is returned in this case.

If either or both of the parameters n and q is non-numeric, then a symbolic group representing the indicated special unitary group is returned.

The standard notation SU(n, q) is also available as a synonym.

In the Standard Worksheet interface, you can insert this group into a document or worksheet by using the Group Constructors palette.
