Palpatine, you are showing that this is a traceable network, I don't think that is what we're going for here. Is the problem to show that you can 'go over' (trace) the network itself and cover every line without overlapping, like what Palpatine is doing (...I think)? Ie draw the rectangle and its accompanying segments without lifting up your writing utensil or going over the same segment twice. Or is it to prove whether or not a continuous curve (a rather insane curve) can pass through all of the small segments only once? That's what I'm trying to do...and if you say that it is impossible, that claim is insatiable without a proof.
