What is Combination Generator?
Combinations are unordered subsets: choosing apple and banana is the same as banana and apple. This tool builds every C(n, k) subset from your input items and prints them line by line. Output is capped at 10,000 entries so large inputs do not freeze the browser; the status line tells you when the cap was hit.
FAQ
- What is the difference from permutations?
- Combinations ignore order — 'a, b' and 'b, a' count as the same subset. Permutations treat the two orderings as different.
- Can I get k = 0?
- k must be at least 1. To list every subset of every size, run the tool repeatedly for k = 1 through the size of your list.
