Usually, the answer to a question about the number of ways to arrange 6 items would be answered 6*5*4*3*2*1 = 6! = 720. However, necklaces may be turned around, so you only have 720/2 = 360 possible necklaces.
How many necklaces are in 7 beads?
It would be 7! = 5040 diffrent necklaces.
How many necklaces can be formed with 8 beads?
The number of ways in which 8 different beads be strung on a necklace is. 2500. 2520.
How many necklaces can you make with 10 beads of colors?
This is easy: count all permutations of 10 beads, 10!, then divide by 20 because we counted each permutation 10 times due to rotation, and counted each of these twice because you can flip the necklace over. Thus the answer is 10!/20 = 181440.

What are the number of ways in which 10 beads can be arranged to form a necklace 9 !/ 2 9 10 10?
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.
