Each of 49 numbers is unique. The number of different combinations of 6 chosen at a time is

_{49}**C**_{6}= 13,983,816.That's how many distinct subsets there are. For any given subset (combination), there are then 6! = 720 orders in which they may be placed; if, however, the six are presented in ascending order, then that's just one possibility (of the particular combination of six).
