Permutation Generator FAQ
What is the difference between combinations and permutations? +
In permutations, order matters, so A-B and B-A are different. In mathematical combinations, those two selections are the same.
Can values repeat in a permutation? +
Yes, when Allow repetition is enabled. Otherwise each input item can appear at most once in each result.
Why is output limited? +
Permutation counts grow extremely quickly. The browser tool limits generated output to protect the page from very large memory and rendering costs.
