PERMUTATIONA function

Description

PERMUTATIONA(number,number_chosen) returns the number of permutations for a given number of objects (with replacement) that can be chosen from the total objects. Mathematically, it is equivalent to raising the total number of objects to the number of objects being chosen.

With number = n and number_chosen = k, the formula for the PERMUTATIONA function is:

• If any argument is not an integer, it is truncated.

• The arguments cannot be negative.
