# PERMUTATIONA

The PERMUTATIONA function calculates the number of permutations for a given number of objects taken from a set with repetitions.

## Syntax ðŸ”—

=PERMUTATIONA(`Number`

, `Number_chosen`

)

`Number` | The total number of objects to choose from. |

`Number_chosen` | The number of objects to choose in each permutation. |

## About PERMUTATIONA ðŸ”—

When the need arises to explore the various ways objects can be arranged in a set, the PERMUTATIONA function in Excel offers a convenient solution. This function is particularly useful when dealing with scenarios involving the arrangement of items where repetitions are allowed. It assists in calculating the total number of possible permutations when choosing a specific number of objects from a set with repetitions considered. Whether you're delving into combinatorial problems or seeking to ascertain the arrangements of elements in a sequence, PERMUTATIONA stands as a reliable asset in your Excel toolkit.

## Examples ðŸ”—

If you have a set of colors {Red, Green, Blue} and need to calculate the total permutations of selecting 2 colors with repetitions allowed, you can use the formula: =PERMUTATIONA(3, 2). This will give you the total number of ways the colors can be arranged in pairs considering repetitions.

Suppose you have a string 'XYZ' and want to determine the number of unique permutations when choosing 2 characters at a time with repetitions allowed. The formula to use would be: =PERMUTATIONA(3, 2). This will provide you with the total number of distinct two-character permutations from the string 'XYZ'.

## Notes ðŸ”—

Ensure that the values provided for the `Number`

and `Number_chosen`

arguments are non-negative integers. The result returned by PERMUTATIONA corresponds to the total number of permutations, taking into account repetitions when selecting objects from a set. Utilize this function for scenarios where you need to explore the various possible arrangements of objects while considering the presence of duplicates or repetitions.

## Questions ðŸ”—

**What does the PERMUTATIONA function calculate?**

The PERMUTATIONA function calculates the total number of permutations possible when choosing a specific number of objects from a set with repetitions allowed.

**Can the PERMUTATIONA function handle scenarios involving repetitions?**

Yes, the PERMUTATIONA function is specifically designed to handle scenarios where repetitions are allowed in selecting objects for permutations. It considers the presence of duplicates when calculating the total number of possible arrangements.

**What type of values should be provided for the arguments of the PERMUTATIONA function?**

The arguments for the PERMUTATIONA function should be non-negative integers representing the total number of objects to choose from and the number of objects to choose in each permutation.
