However, such an object can be defined as follows. The relation of having the same cardinality is called equinumerosity, and this is an equivalence relation on the class of all sets. The equivalence class of a set A under this relation, then, consists of all those sets which have the same cardinality as A. There are two ways to define the "cardinalit…

WebSo, we write that one subset into the power set to get. P ( ∅) = { ∅ }. Notice the empty set contains 0 elements, while its power set contains 2 0 = 1 elements.
