👉 The term "hiliferous" refers to a type of mathematical object that is defined by a set of points in a plane, and each point on the set is connected to exactly two other points. This concept is named after the ancient Greek mathematician Euclid, who described a set of points where every pair of these points are connected by at least one line segment. The term "hiliferous" is often used to describe this type of geometry in modern mathematics and computer graphics.
