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.
The required minimum number of strokes is 14.
