Orders of Finish (Posted on 2008-01-12) Difficulty: 3 of 5
In a race among 10 contestants, how many orders of finish are there, counting possibilities of ties?

For example, in a 4-person race, A and B finishing at the same time, before C and D finish simultaneously, is a different order from C and D finishing together before A and B finishing together, and of course each of the 4! ways of all finishing separately are different orders.
