File:Wild3.png

Summary
This wild arc is topologically the same as the example given in the Hocking and Young book. It differs from Wild1.png because the overpass and underpass sequence is over/over/under/over/under/under (starting from the topmost point and following the curve to the right), whereas the sequence for Wild1.png is over/under/over/under/over/under. These curves look the same if you ignore the overpass/underpass sequence, but they are not topologically equivalent.

In the Hocking and Young book (page 177), the diagram they give is a left-right mirror image of the image Wild3.png which is given here. The reason for the mirror-reversal here is to facilitate comparison with File1.png, which matches the current example on the "Wild arc" wikipedia page.
