This classification examines hexagonal 3-webs with polar curves on a sphere, demonstrating their relationship to twisted cubic properties.
The paper describes and classifies hexagonal circular 3-webs on unit sphere such that the polar points of the web circles lie on a twisted cubic, thus completing classification of hexagonal circular 3-webs with algebraic polar curves of degree three.
