The algorithm identifies secant lines based on their intersections with F, revealing distinct categories of non-secant and k-secant lines. Additionally, we partitioned the point set of F into three subsets, uncovering geometric configurations and forming 5-gons related to perspectively. This analysis offers new insights into the structure of the Klein cubic threefold and its geometric properties.}, number={3}, publisher={Erzincan Binali Yildirim University}
