What is the minimum number of strokes to reproduce the drawing below without lifting up the pencil from the paper (no tricks at all), and without passing over a line segment (or part of it) already drawn? You may begin and end wherever you like, and line segments may cross each other, but only as intersections.

Note: a new stroke occurs when a line type ceased because you have to stop and change direction.

(In reply to re(6): No Subject by Charlie)

Charlie, IŽll not argue with you about "semantics". You know what is a stroke. And if you trace only one line, thereŽs no stroke at all.

And the note was written by the JM.
