Power set

A power set is the collection of all possible subsets of a set. For example, if you have a set with three items—say, {A, B, C}—the power set includes every combination of these items: {}, {A}, {B}, {C}, {A, B}, {A, C}, {B, C}, and {A, B, C}. The power set essentially represents every way to choose any number of elements from the original set, including choosing none (the empty set) or all of them. It provides a comprehensive view of all possible groupings within the original set.
