Using qombinatorics

The user interface is really simple and intuitive.

1. This is the output window;
2. Clicking you can change the tab, switching form combination to permutation calculus and viceversa;
3. You can change the input parameter writing in the spinbox, using the arrows or the slider;
4. Click this checkbox to include or discard repetitions;
5. This button executes calculations;
6. Bye bye, qombinatorics!

The results can be copied and pasted as usual.
