So would I be correct in assuming, that if I had twenty different programs, and could only access four of them at a time, that I would multiply 20 X 19 X 18 X 17; which equals 16,279,200 to find out many different ways I could arrange them?

If so, I think I got the hang of it.

You are quite correct. The two questions were different.

And giving the correct answer to a problem, however old it may be, is always good.
