About this app
Combinatorics can calculate and enumerate all possible permutations, combinations, ...
Combinatorics algorithms:
* Permutations of letters
* Anagrams of words
* k-Permutations of letters
* Combinations of letters
* Combinations with repetitions of letters
Extra features:
* Displays the number of permutations/combinations/... with well formatted mathematical symbols using tex/latex
* Ability to share a calculation, for instance to save it to a file or to mail the result
* Unicode support, so letters of non latin alphabets and emoticons are also supported
* Option to send feedback from within application
Translations:
* English
* Dutch
* Portuguese

Very good app. Please include a highlight option to copy and paste so it can be directly transfered to ms word. Also, symbols like +, -, *,/ , e.t.c, to get should be able to be inputed to know how many places a sign can be in a combination. E.g A+B-C and A-B+C and so on. Also, numbers like 10 and above are splited as 1 and 0. Lastly, once the letters exceed z, signs should be inputed like π,£, e.t.c. I really love this app and appreciate your team!

Previously it was so good but now it takes huge time to process. It's working so slowly . Please make the app fast as before.

There is indeed a slowdown at the start of the generation. For very large generations there is also a slowdown. We are looking into this. Otherwise all the functionality of the previous version should still be available.
Hang tight for the optimizations to come.

While i appreciate the effort, it does not show part permutations without repeats. Who cares that you can show the same letters in many repetitive ways? IE with "banana" you can show aa in 6 different ways! So what? And there's no choice. Please rectify to make it more interesting and useful. Anagrams show different combinations but only using all the letters. Why can't anybody get it right?

We implemented all standard combinatorics algorithms. What extra kind of combinatorics would be helpful for you? Could you mail directly from within the program, see the feedback options. Maybe give an example of the kind of result you need.
