Well, this is not possible on any computer, as there are >10^10 of them,
and each needs few kilobytes to be stored...

Well, the problem of computing *one* Sylow 3-subgroup of G
seems to be well within reach of your particular hardware - I can do
this on my Pentium 90 with 24 Mb, the computation would take few hours
though. The real difference is that I'm running Linux 2.0 instead of
Win95...
Install Linux (which is better system for all sorts of computational
problems anyway), and at least questions of computing such a subgroup
would be easy...

Thanks in advance.
