List every subset of up to 13 items, including the empty set. A set of n items gives 2ⁿ subsets, one per line.

This tool runs open-source code from CyberChef by GCHQ (Apache License 2.0). See open-source credits.

For n input items, the enumeration contains 2ⁿ subsets, including the empty subset.

The result lists subsets on separate lines. A blank first line represents the empty subset.

  • List every combination of optional features, such as feature flags to test together.

List the subsets of a,b

Input: {a,b}

Settings: Comma-separated members.

Result: {} {a} {b} {a, b}

Separate items and interpret the empty subset

  1. Enter items with the selected Item delimiter.
  2. Remove duplicate items when you need a mathematical set.
  3. Run the calculation and inspect the subset list.
  • Spaces remain part of each item.
  • The output orders by text length, not subset size.
  • Empty input returns empty output.
