The receptacles are convex to conic and honeycombed. Let ABCDEF be a hexagon formed by six tangent lines of a conic section. A generalization of a non-degenerate conic in a projective plane is an oval. There are some authors who define a conic as a two-dimensional nondegenerate quadric. The name "parabola" is due to Apollonius, who discovered many properties of conic sections. A point on just one tangent line is on the conic. A von Staudt conic in the real projective plane is equivalent to a Steiner conic. This determinant is conventionally called the discriminant of the conic section. Alhazen eventually solved the problem using conic sections and a geometric proof. The algorithm can be generalized to conic sections. Back, legs and tail with prominent conic tubercles. This allows for two dimensional columnar ordering, for both discotic and conic LCs. Its most salient content is all the basic definitions concerning cones and conic sections. No continuous arc of a conic can be constructed with straightedge and compass.
