Overview of Magma V2.14: Groups

3.1.4 Conjugacy Classes. The conjugacy classes of elements of a group G are found using a lifting algorithm which first finds the classes of the trivial Fitting quotient of G and then lifts these classes through the layers of an elementary abelian series for G.For example, all classes in the group 2 12.(SL 2 (4) ≀ S 3) of degree 4096 and order 5,308,416,000 are computed in 4 seconds.
