'''
The system clock seed gave us an idea that reduced the number of
possible shuffles even further. By synchronizing our program with the
system clock on the server generating the pseudo-random number, we are
able to reduce the number of possible combinations down to a number on
the order of 200,000 possibilities. After that move, the system is
ours, since searching through this tiny set of shuffles is trivial and
can be done on a PC in real time.
