# Powerset generator

World's simplest set tool
With this online application, you can quickly find the power set P(S) of the given input set S. As the power set for an n element set is made out of 2

^{n}subsets, the input set size is limited to 16 elements, which will generate 65,536 subsets. In the options, you can control the generation order of subsets and also the order of elements within subsets. You can also customize the looks of the output power set and individual subsets.

## What is a powerset generator?

learn more about this tool
This browser-based program generates all subsets of the given set. This is called the powerset and it includes the empty set and also the set itself. Given the set A, the usual notation for the powerset is P(A) or if you love fancy things, also 𝒫(A) and ℙ(A). If the cardinality (number of elements) of the input set A is n, then the powerset is made out of 2

^{n}elements. The number 2^{n}grows exponentially fast and for just 10 element set it already exceeds 1000. By default, the powerset generator prints subsets from the one with least elements to the one with most elements – first, it's the empty set, then the singleton subsets, then the two-element subsets, and so on. You can also change the order of this output in the options and display subsets from the one with most elements to the one with least elements or print them in random order. You can also change the order of elements in the subsets – they can go from left to right, from right to left, or in random order. As different programming languages use different syntax for sets, you can also customize the format of the output subsets – you can change the open-set symbol "{" and the close-set symbol "}" and change the set element delimiter "," to something else.

Click to usePowerset of 4 Elements

In this example, we generate a powerset from a four-element set. The elements of this set are digits from 1 to 4 and the set is entered using standard mathematical notation, where commas separate the elements and the set is enclosed in curly brackets. The powerset of a set of four elements creates 2

^{4}= 16 subsets. We generate them in order of their cardinality (from the smallest subset to the largest subset) and also use the standard set format in the output.

Power Set of the Alphabet

This example loads a set of first five English letters as input elements and returns the power set of 32 sets in the output. It changes the subset order in the output and first prints the 5-element set with all the letters (same as input set), then all possible 4-element sets with all possible four-letter combinations, then all possible 3-element sets with three letters, then 2-element sets with two letters, then 1-element sets, and then the only 0-element set (null set). It also changes the letter order and takes the elements from the input set from right to left when creating subsets. It uses angle brackets as set-open and set-close characters, removes separators between set elements, and prints all subsets on one line, separated by commas.

Unicode Powerset

In this example, we enter a very unusual set in the input and get an even more unusual powerset in the output. Each element of the input set is a Unicode fruit emoji. As the input emojis are separated by spaces and there are no open/close set symbols around the set elements, in the options we use the space character as the input element separator and leave the open/close set character fields empty. Additionally, we use the bold curly brackets to enclose the fruit subsets and put the "❌" symbol between subset elements.
