How are you supposed to go about putting together the power set of a set of sets such as
X = {{1},{1,2}}
What is the power set of X then? And what's the rule for calculating cardinality for the power set of a set that consists of elements which are sets such as the above? Because the set X to my understanding has 2 elements, both of which are sets... so the power set of X doesn't consist of only 4 elements, does it?
There are:
{}, {1}, {1,2}, {{1},{1,2}}
Or is that really all?
Please help clarify this to me, thanks so much.
