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(8): No Subject by Charlie)

Again, I have no dictionary by now. The whole text was written by the JM. You could be there when the problem was in the queue.

And I didnīt argue with Percy. I corrected what she thought was 15 strokes.
