👉 Sesperal is a concept in mathematical notation used to represent an infinite series of points that form an ellipse. It was introduced by Carl Friedrich Gauss, who defined it as the limit of a sequence of nested circles around a point. In this context, "sesperal" refers to a sequence of concentric circles that are centered at a given point and each have radii (diameter) equal to the distance between two points on the outermost circle. The limits of these circles continue
