WebIn mathematics, permutation is a technique that determines the number of possible ways in which elements of a set can be arranged. For Example, the permutation of Set Z = { 1, 2 } is 2, i.e., { 1, 2 } and { 2, 1 }. We can see from this example that these are the only two possibilities in which the elements can be arranged. WebThere are 4 mutually exclusive ways of permutation that add to the solution: Permutation of all different letters: 8! 4! =1680 Permutation of 2 from 5 letters (excluding all 3 duplicates), HEICS, and then each of this permutated with each pair of duplicates.
WebTo calculate the amount of permutations of a word, this is as simple as evaluating #n!#, where n is the amount of letters. A 6-letter word has #6! =6*5*4*3*2*1=720# different permutations.
