A set of points is a collection of points in a given space. The term 'set of points' can be abbreviated to LOCI (4 letters) or LOCUS (5 letters). It is often used in mathematics and geometry to refer to a group of points that have a common property or relationship. In geometry, a set of points can be used to define a line, a circle, or a polygon. In algebra, a set of points can be used to represent a function or equation.
