The PERMUTATIONA function returns the number of permutations for selecting a group of objects (with replacement) from a total number of objects. Mathematically, it is equivalent to raising the total number of objects to the number of objects being chosen.
Parts of a PERMUTATIONA function
||Required. The total number of objects to choose from.|
||Required. The number of objects to choose from number. Must be less than or equal to number.|
- Both arguments are truncated to integers.
- If the number is zero,
PERMUTATIONAreturns a #NUM.
Result for A1=
PERMUTATIONA(3, 2), A2=
PERMUTATIONA(3.2, 2), A3=
Note: All functions return the same result due to truncation.
- PERMUT: Returns the number of ways to choose some number of objects from a pool of a given size of objects, considering order.
- COMBIN: The COMBIN function returns the number of ways to choose some number of objects from a pool of a given size of objects.
- COMBINA: The COMBINA function returns the number of ways to choose some number of objects from a pool of a given size of objects, including ways to choose the same object multiple times (also known as choosing with replacement).
