Factorial 7 (7!) ie 7 x 6 x 5 x 4 x 3 x 2 = 5040 different ways. Look at it this way: The first place can be taken by any of the 7 objects, which leaves any of 6 objects available for second place, which leaves any of 5 objects...
8 different objects can be lined up in (8 x 7 x 6 x 5 x 4 x 3 x 2) = 40,320 different ways.
