Streets in Equilateralville are arranged in equilateral triangles as illustrated. Darlene walks to work every day making sure that each pathway she uses takes her clower, in actual distance, to work. Justin just wants to use a different route every day, without retracing a pathyway he has already taken and without going through the same intersection point wice. Find the difference between the number of pathways Darlene uses and the number of Justing uses if both start from point A and work is at point W.
