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.

"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."

Yes I know what is a stroke.  But you did argue semantics, in "correcting" Percy. The only dictionary definitions relevant to this are:

<DIR> <DIR>

11. a single complete movement, esp. one continuously repeated in some process.

15. a movement of a pen, pencil, brush, graver, or the like.

16. a mark traced by or as if by one movement of a pen, pencil, brush, or the like.
