The possible ways of arranging a line of eleven people is equivalent to the number of permutations of eleven things taken eleven at a time. That is eleven factorial, or 39,916,800.
6! = 720
3 items (or people) can line up in 6 different sequences. 6 items (or people) can line up in 720 different sequences.
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 24 ways to arrange 4 people in a row.

6! = 720
3 items (or people) can line up in 6 different sequences. 6 items (or people) can line up in 720 different sequences.
That would be 5x4x3x2x1 or 5! or 120 ways to arrange those objects in a line.
24 different ways.
