Using graph theory, each row of trees is drawn with three edges. The degrees of the vertices of the outer octagon is 5, middle octagon 6, and inner octagon 10. The sum of all the degrees is 8*(5+6+10)=168. The number of edges is 168/2=84. Lastly, the number of rows of trees is 84/3=28. Thanks for the cool counting problem. | |
