# PERMUTATIONA

Formulas / PERMUTATIONA
Calculate the number of permutations with repetitions.
`=PERMUTATIONA(number,number_chosen)`
• number - an integer that describes the number of objects in a dataset
• number_chosen - an integer that describes the number of objects in each permutation

## Examples

• `=PERMUTATIONA(3,2)`

Using the function in Sourcetable, you can calculate the number of permutations for a group with 3 objects that have 2 objects selected from the total objects. This function returns the number of permutations for a group with 3 objects, where 2 objects are selected from the total objects.

• `=PERMUTATIONA(2,2)`

Using the function in Sourcetable, you can calculate the number of permutations for a group with 2 objects. This function returns the number of permutations for a group with 2 objects, where all of the objects are selected from the total.

## Summary

The PERMUTATIONA function is used to calculate the number of permutations for a given set of objects. It requires two arguments, the total number of objects and the number of objects in each combination.

• The PERMUTATIONA function returns the number of permutations of a given number of items, including repetitions of a value.
• To calculate the number of permutations without repetitions, use PERMUT.
• A permutation is a combination where order matters and there are two types of permutations: permutations where repetition is not allowed and permutations where repetition is allowed.
