# PERMUT

## Content

This function returns the number of possible permutations for a specified number of items.

## Syntax

`PERMUT(k, n)`

## Arguments

This function has these arguments:

| Argument | Description |
| -------- | ----------- |
| *k* | Number of items; must be greater than 0; if not an integer, the number is truncated |
| *n* | Number of items in each possible permutation; must be positive or 0; if not an integer, the number is truncated |

## Remarks

A permutation is any set or subset of items where internal order is significant. Contrast with combinations (the [COMBIN](/spreadjs/docs/v16/formulareference/FormulaFunctions/math-trig-functions/COMBIN) function).

The equation for this function is:

where k and n are defined in the arguments.

## Data Types

Accepts numeric data for both arguments. Returns numeric data.

## Examples

`PERMUT(B3,5)`

`PERMUT(C4,B2)`

`PERMUT(R1C2,2)`

`PERMUT(8,2)` gives the result 56

`PERMUT(100,3)` gives the result 970200
