construct a permutation group isomorphic to a projective special unitary group
ProjectiveSpecialUnitaryGroup( n, q )
PSU( n, q )
a positive integer
power of a prime number
The projective special unitary group PSU⁡n,q , over the field with q2 elements, is the quotient of the special unitary group SU⁡n,q by its center.
Note that for n=2 the groups PSU⁡n,q and PSL⁡n,q are isomorphic. These groups are soluble being isomorphic, respectively, to the symmetric group of order 6, and the alternating group of order 12. Furthermore, the group PSU⁡3,2 is a Frobenius group of order 72 and is soluble. For all other values of n and q, the group PSU⁡n,q is simple.
The ProjectiveSpecialUnitaryGroup( n, q ) command returns a permutation group isomorphic to the projective special unitary group PSU⁡n,q .
If either or both of the arguments n and q are non-numeric, then a symbolic group representing the projective special unitary group is returned.
The command PSU( n, q ) is provided as an abbreviation.
In the Standard Worksheet interface, you can insert this group into a document or worksheet by using the Group Constructors palette.
