     Here is a hint to help you on your way to finding solutions to
the previously posed puzzle: any chord of a circle can be represented by
its midpoint. Therefore this helps in two ways: it is possible to generate
random chords by generating random points, and a simple check for
intersection with the inner circle is to check if the midpoint of the chord
is in the inner circle. This should help considerably, and make evident
yet another solution to the puzzle. However, we found more solutions based
on this property also, see if you can find them.

                                        Happy puzzling,
