A push-button padlock 2010-01-17
From Vince:
Hi,

I have a push-button padlock using ten buttons (1-2-3-4-5-6-7-8-9-0). Five digits must be pushed in order to open the lock. Each digit can only be used once. Order is not supposed to matter.

How many different possible combinations? And what are they?
