👉 Bestead is a term used in the context of mathematics, specifically in the field of geometry and topology. It refers to the largest open set (or surface) that can be constructed from two given sets without overlapping or intersecting with them. In other words, it represents the largest possible region that can be covered by two shapes without any overlap or intersections. Besteads are often used in topology and geometry to represent surfaces and topological spaces. They are also used in computer graphics and computer vision
