👉 In mathematics, "xyloses" is a mathematical expression used to represent a set of points in a plane that are at a fixed distance from another point or line. This can be thought of as an extension of the concept of "closed" and "open" sets, where closed means that all points in the set are connected by a path, while open means that some points in the set cannot be reached from any other point. For example, if we have a plane with two points A and
