👉 In mathematics, an "epipanion" is a subset of a topological space that can be placed with respect to one or more additional points (called "epipanes") in such a way that it contains all its limit points. In other words, the set of epipanies encloses all limit points. For example, consider the real line $\mathbb{R}$ and let's say we want to define an epipanion around $0$. We can
