Wrong: 49!/43! which IS less than 49^6
10068347520 < 13841287201
The Logic: First pass there are 49 balls to choose from.
Second pass there are now only 48 balls 
etc.
Thus: 49*48*47..*1=49!
But we'll stop after 6 tries: thus eliminate every thing after the 49-6'th try
Thus: 49!/43!=49*48*47*46*45*44

But it's still a biggish value :(
