The difference between combinations and permutations is that permutations have stricter requirements - the order of the elements matters, thus for the same number of things to be selected from a set, the number of possible permutations is always greater than or equal to the number of possible ways to combine them. With combinations we do not care about the order of the things resulting in.
The possible number of arrangements for all n people, is simply n!, as described in the permutations section. To determine the number of combinations, it is necessary to remove the redundancies from the total number of permutations (110 from the previous example in the permutations section) by dividing the redundancies, which in this case is 2.
Today I have two functions I would like to demonstrate, they calculate all possible combinations from a cell range. What is a combination? To explain combinations I must explain the difference between combinations and permutations. Think of permutations as if the order is important and combinations as if the order is not important. If this is confusing, look at the following examples. Example.
To calculate the number of possible combinations in dominoes, use the formula for combinations where order does not matter and repetition is allowed. Because order does not matter, a domino with three dots on one side and two dots on the other is the same as a domino with two dots on one side and three dots on the other. Repetition being allowed means that you can have a domino with the same.
How to Use the Combination Calculator? The procedure to use the combination calculator is as follows: Step 1: Enter the value of n and r in the respective input field. Step 2: Now click the button “Calculate Possible Combinations” to get the result. Step 3: Finally, the total number of possible combinations will be displayed in the output field.
If you need to generate all possible combinations based on multiple columns data, maybe, there is not a good way of dealing with the task. But, Kutools for Excel's List All Combinations utility can help you to list all possible combinations quickly and easily. Click to download Kutools for Excel!

How to Calculate Permutations and Combinations You don’t need to be a math whiz to be a good programmer, but there are a handful of equations you will want to add to your problem solving toolbox. In this tutorial, you learned how to calculate permutations and combinations of a series of n integers with simple and easy to remember equations.
