Hi, Dylan.

Consider the triangulations of a pentagon.  There a 5 triangulations, and if you
connect two triangulations that share a triangle, you get a 5-cycle.

I'm pretty sure you mean the triangulations that don't add a vertex, right?

In other news, how are you?  Any chance of my gettting to see you -- and possibly meet Ken -- when you're in town this month?

Best regards,
