The first can be any one of 15 cheerleaders. For each of those . . .
The second can be any one of the remaining 14. For each of those . . .
The third can be any one of the remaining 13. For each of those . . .
The fourth can be any one of the remaining 12. For each of those . . .
The fifth can be any one of the remaining 11.
The total number of permutations is (15 x 14 x 13 x 12 x 11) = 360,360 .
But . . .
Once you have five people on a squad, the order in which they were chosen doesn't matter.
If you have A-B-C-D-E standing there, it's the same group of kids as A-B-C-E-D. So for each
squad of five, they could have been chosen in (5 x 4 x 3 x 2 x 1) = 120 different ways.
There are 360,360 different ways to choose squads of 5, but only (360360/120) = 3,003 different squads.

Did the Pittsburgh Steelers ever have cheerleaders?
The Rooney family is classy. I can't find a reason but at one time they did. They were called the Steelerettes (steelerettes.com) and were a squad chosen from a local junior college. Once the junior college had their own football team, the Steelerettes disbanded. They were the official squad from 1961-1970. The Steelers were actually one of the first teams to ever have cheerleaders. They were named (are you ready for this?) The Steelerettes. How clever. They were basically a gimmick created to take attention away from how awful the team was. The squad only stuck around for about 8 years (61-69) before they were disbanded. As for why they don't have a squad now, can you imagine trying to find a group of attractive women who would be willing to bounce around in short skirts in the middle of December in Pittsburgh? They'd have to be crazy.
