PERMUT(n,nc)

• $n$ and $nc$ are integers

Description

• This function gives the number of Permutations for a given number of objects.
• A permutation, also called an "arrangement number" or "order", is a rearrangement of the elements of an ordered list.
• A selection of objects in which the order of the objects matters.
• A Permutation is an Ordered Combination.
• In $PERMUT(n,nc)$, $n$ is an integer which is indicating the number of objects and $nc$ is an integer which is indicating the number of objects in each permutation.
• For $n$ and $nc$, when we give in decimals, it will change into integers.
• The formula for the number of permutation is: $_{n}P_{k}={\frac {n!}{(n-k)!}}$
• The Permutation is denoted by $_{n}P_{k}$, $P_{n,k}$, or $P(n,k)$.This function will give the result as error when

1.$n$ and $nc$ are non-numeric.
2.Suppose $n\leq 0$  or  $nc<0$ or $n<nc$.

Examples

1. =PERMUT(14,2) = 182
2. =PERMUT(50,5) = 254251200
3. =PERMUT(10.2,3) = 720
4. =PERMUT(4,0) = 1
5. =PERMUT(6,1) = 6
