👉 In mathematics, a supergroup is a set of subsets of a topological space that are closed under certain operations. The concept of supergroups was introduced by John von Neumann and includes the following properties: 1. Closure under union: For all sets $A_1$ and $A_2$, if $A_1\cup A_2 = U$, then so is $A_1 \cap A_2$. 2. Closure under intersection: For all sets $A
