17-gon In A Circle

A circle is drawn and 17 distinct points are chosen on it.
Each pair of these points is connected by a chord (136 line segments in total).
The points are chosen in such a way that no more than two chords intersect at the same point.
These chords divide the interior of the circle into many regions.

How many regions are there?

This problem is based on a FB discussion I had with Will Heierman.
