Qiaochu's answer (and your comment on it) have given me everything I need. | |
| Jul 9, 2016 at 8:30 | comment | added | Derek Holt | If you were looking for a practical algorithm, then you would need more information on the input. Are the entries in the matrices given as algebraic numbers? Is the group sufficiently small that you can readily compute with it, such as finding representatives of its conjugacy classes? | |
