Power Set

Power set

P(A) contains every subset of A, including ∅ and A itself. For n distinct elements it contains 2ⁿ subsets. Selecting size k shows subsets with exactly k elements; it does not change P(A).

Enter string values separated by spaces, commas or semicolons; outer braces are optional. Quote values containing separators or braces. Within quotes, escape quotes and backslashes with a backslash. An empty quoted string is an element; blank input is the empty set. Duplicates count once; case and spelling matter.

Calculate accepts at most 12 distinct values and 4,000 characters. Results have 64 subsets per page; use Page or Previous/Next to explore all of them. Editing clears the result; saved input does not calculate automatically.
