From Wikipedia, the free encyclopedia:



    In mathematics, the power set (or powerset) of any set S is the set of all subsets of S, including the empty set and S itself.

    https://en.wikipedia.org/wiki/Power_set

If the given set has n elements, then the power set has elements.

What is written in your post and what does it mean, is difficult understand to me.

Still, I hope and expect, that my response is clear and understandable.

See the lesson
- How many subsets are there in a given finite set of n elements?
