    please help! toroidal trouble

    can anyone please explain to me the easiest way to find toroidal drawings for a given graph. i have been trying for hours to find one for K4,4 and K7. is it really just a trial and error type of thing? this is so frustrating. there must be an easier way.

    a non planar graph is said to be toroidal if it can be drawn on the torus so that no two edges cross.
