It is trivial and well known how to compute this. So this paper is perhaps weak evidence that the structure in general is not known so far. | |

| Aug 24, 2013 at 13:52 | comment | added | Jim Humphreys | Finite group theorists have done a lot of explicit work from the viewpoint of algebraic groups. But it may be important to distinguish cases where $n$ is even or not, and especially the case when $n$ is a power of 2. In this last case, the recent book by Liebeck-Seitz on unipotents and their centralizers might be helpful. It's also worth checking the older LNM #131 article by Springer and Steinberg. | |
