These Fundamental Lines intersect at the Primary Points and at 45 other points called the Diagonal Points. These are the diagonal points of the quadrangles formed by four of the Primary Points, three for each quadrangle. The next figure shows the Diagonal points in yellow.
The Fundamental Lines Intersect off the Conic at the Diagonal Points.
Each Fundamental Line meets the fourteen others in 8 points; 4 at each of its Primary Points and in 6 Diagonal Points. You can move the Primary Points to check this out.
