1. The problem is to find the power set of a given set, but the set itself was not specified in your question. 2. The power set of any set $S$ is the set of all possible subsets of $S$, including the empty set and $S$ itself. 3. For example, if $S = \{a, b\}$, then the power set $\mathcal{P}(S)$ is: $$\{\emptyset, \{a\}, \{b\}, \{a, b\}\}$$ 4. The number of subsets in the power set is $2^{n}$ where $n$ is the number of elements in $S$. 5. If you provide the set you want the power set for, I can help find it specifically.
