I have recently being assigned a problem, part of which involves taking 20
numbers (say) and generating all combinations of 7 numbers from them.  
The closest thing that I can find to the chose(combination) function in 
mathematica is the Permutations[list] function. Is there an easy and efficient 
way of doing this in Mathematica or is there a package available  
that has a choose(combination) function defined in it?
