How many ways can 10 differently colored beads be threaded on a string?
Answer: This is called a cyclic permutation. The formula for this is simply (n-1)!/2, since all the beads are identical. Hence, the answer is 9!/2 = 362880/2 = 181440.
How many ways can 7 different colored beads be threaded on a string?
= 5040 diffrent necklaces.
How many different necklaces can be formed using 9 different Coloured beads?
This leaves us with 18,150 – 6 = 18,144 strings. The total number of necklaces we can form with these strings is 18,144 ÷ 9 = 2016.

The first step is easy: the number of ways to colour 6 beads, where each bead can be red, green or blue, is 36 = 729. Next we put the beads on a necklace, and account for duplicate patterns.
How do you find the permutation of 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. To write out all the permutations is usually either very difficult, or a very long task.
