Permutation & Combination Generator
List the actual combinations, permutations, or subsets of a set of items — not just the count. Enter your items (comma- or newline-separated), pick a mode, and the tool enumerates every result. Combinations are unordered selections, permutations are ordered, and the "with repetition" variants let an item be used more than once. The companion to the Combinatorics Calculator (which counts these). Everything runs locally in your browser.
Counts use exact big-integer arithmetic, so they're correct even when astronomical (e.g. P(20,10) or 230). To keep the page responsive, at most 4096 results are listed — when there are more, the first 4096 are shown and the count tells you the true total. Duplicate items are kept as you entered them (they count as distinct positions). Everything runs locally — nothing leaves your browser.
