It's explained in http://en.wikipedia.org/wiki/B%C3%A9zier_curve

But by far, the most common are order 2 (Tcl/Tk, TrueType, etc) and order 
3 (Illustrator, PDF, etc) and there's a reason for that. They become 
increasing complicated and hard to handle as the order increases, and I 
don't mean the computation time : even though computation time does 
increase a lot with the order, it's not as radical as the decrease of your 
ability to figure out the parameters to make the curve go where you want 
it to go, because it looks less predictable.

So, usually, when they have more than four dots, people chain together 
pieces made from three or four dots each.
