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.
