👉 The term "exactors" is a mathematical concept in topology and geometry. It refers to an object that has no holes or breaks at its corners, as opposed to an object with holes or breaks. Exactors are often used in the study of manifolds, which are spaces equipped with a smooth structure, such as curves or surfaces. In topology, exactors can be defined as objects that satisfy certain properties that ensure they do not have any holes or breaks at their corners. For example,
