PERMUT

In This Topic

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

PERMUT(*k*,*n*)

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 |

A permutation is any set or subset of items where internal order is significant. Contrast with combinations (the COMBIN function).

The equation for this function is:

where k and n are defined in the arguments.

Accepts numeric data for both arguments. Returns numeric data.

PERMUT(B3,5)

PERMUT(C4,B2)

PERMUT(R1C2,2)

PERMUT(8,2) gives the result 56

PERMUT(100,3) gives the result 970200
