Permutations of a set of n elements

Calculate the permutations of n objects
  Enter number of objects n=
 
 
OR Enter the numbers separated by commas ( , ) to display all possible permutations.
Sample :
  for example enter : 1,32,5,3,76,43,23,42
 
 
  • The meaning of the "permutation" indicates the ways of ordering n objects
  • (x1,x2,x3,....,xn)= Set of n numbers
    • Number of permutations =1•2•3....•(n-1)•n=n!
  • For example the Permutation of set of numbers (1,3,2) is :
    • 1,3,2
      3,1,2
      1,2,3
      2,1,3
      3,2,1
      2,3,1
