3 items (or people) can line up in 6 different sequences. 6 items (or people) can line up in 720 different sequences.
15C3 = 455
If you keep them in a line, there are 24 ways to line them up. Then of course there are squares, diamonds, rectangles, parallelograms, stacks, etc.
There are 1680 ways of arranging them is a straight line: fewer if in a circle.
you can arrange three beads 9 different ways.

3 items (or people) can line up in 6 different sequences. 6 items (or people) can line up in 720 different sequences.
The number of different ways that you can arrange 15 different items is given by the permutations of 15 things taken 15 at a time. That is 15 factorial, or 1,307,674,368,000.

Any 6 different items can be arranged in 6! (6 factorial) ways. 6! = 6 * 5 * 4 * 3 * 2 * 1 = 720.
24 ways.
