According to this page: https://en.wikipedia.org/wiki/Cantor's_theorem
It says: "Cantor's theorem is a fundamental result that states that, for any set A, the set of all subsets of A (the power set of A) has a strictly greater cardinality than A itself."
Furthermore, it says: "Cantor's argument applies for any set, including countable and uncountable infinite sets."
So my question is: Is the cardinality of the power set of an infinite set equal to: 2∞ ?
Thanks,
Jake
