In addition, the functions
DirectProduct WreathProduct TensorProductprovide the user with a number of standard constructions.
Further, permutation representations of various classical groups may be constructed by setting up a matrix group using one of the standard functions
GeneralLinearGroup SpecialLinearGroup GeneralUnitaryGroup SpecialUnitaryGroup SymplecticGroup SuzukiGroupand then applying the function OrbitImage.
A large number of permutation representations may be found in the companion databases prmgps, which contains primitive groups of degree up to 50, and simgps, which contains permutation generators for all simple groups of order less than a million. See Database of Primitive Groups and Database of Simple Groups: Permutations, Presentations, Conjugacy Classes, Maximal Subgroups and Sylow Subgroups.
