How many permutations are in a word?
To 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.
What is permutation and combination in simple words?
permutations and combinations, the various ways in which objects from a set may be selected, generally without replacement, to form subsets. This selection of subsets is called a permutation when the order of selection is a factor, a combination when order is not a factor.
How many combinations of 3 words are there?
You can extend each of these possible two letter words into a three letter word by adding one of 26 possible letters and hence there are 26 × 26 × 26 possible three letter words.

What are permutations and factorials?
Factorial numbers simply tell you how many possible ways that a specific number of objects can be arranged . An arrangement can also be called a permutation. And then there are combinations. The number of possible arrangements (or permutations) for a specific number of objects is called the factorial of that number.
