👉 In mathematics, a "litster" is a type of object in a mathematical structure. It's a special kind of "ball" that is used to represent points and lines in Euclidean geometry. The term "litter" comes from the Latin word "litterum," which means "book." In this context, "litter" refers to an infinite collection of points or lines, often used as a representation for mathematical structures like spheres, hyperbolas, and other curves.
