GAP listing of the finite subgroups of U(3) of order smaller than 2000

We have sorted the SmallGroups library of all the finite groups of order smaller than 2000 to identify the groups that possess a faithful 3D irreducible representation (irrep) and that cannot be written as the direct product of a smaller group times a cyclic group. Using the computer algebra system GAP, we have scanned all the 3D irreps of each of these groups to identify those that are subgroups of SU(3); we have labeled each of these subgroups of SU(3) by using the extant complete classification of the finite subgroups of SU(3). Turning to the subgroups of U(3) that are not subgroups of SU(3), we have found the generators of all of them and classified most of them in series according to their generators and structure.
