Two of the heptagrams are centered in the middle, while the other fourteen are smaller, and form a ring around the two in the center.

Ten Pentagrams
The ten pentagrams meet at a common vertex in the center.
Fourteen Heptagrams
The fourteen heptagrams, also known as {7/3} star heptagons, meet at a common vertex in the center of the whole diagram. I did the math using Geometer’s Sketchpad, and then colored the result using MS-Paint.
