Dear Marek, dear Forum, The full character tables for E7(2) and E8(2) are still not known. With the mathematical and computational techniques we have today, it may be possible to compute them; but one cannot be sure before trying it (it is on a TODO list). In the moment you can find some information on my webpage. Some information on conjugacy classes, centralizers and all character degrees is here: http://www.math.rwth-aachen.de/~Frank.Luebeck/chev/E72.html http://www.math.rwth-aachen.de/~Frank.Luebeck/chev/E82.html In fact, you can find most of this information even for all E7(q) and E8(q): http://www.math.rwth-aachen.de/~Frank.Luebeck/chev/nrclasses/nrclasses.html http://www.math.rwth-aachen.de/~Frank.Luebeck/chev/DegMult/ > I am also interested to see where I can find sizes of involution classes in > these groups. But this is probably question to other mailing list. See http://www.math.rwth-aachen.de/~Frank.Luebeck/chev/23elts.html and the references given there. This describes which classes on the E7(2) and E8(2) pages are involution classes.
