Dear All, Since I am new to Mathematica, I apologise if this question is trivial!! I am trying to list all the subsets of a set of variables, ie I have a set X containing 4 variables X1, X2, X3 and X4 - so what I want to do is list all the subsets, so for this case it would be: X1 X2 X3 X4 X1,X2 X1,X3 X1,X4 X2,X3 X2,X4 X3,X4 X1,X2,X3 X1,X2,X4 X1,X3,X4 X2,X3,X4 X1,X2,X3,X4 The problem is as the set becomes larger, there are 2^n possible subsets, as such I would like to know if there is a quick way of displaying this information in this format. Thanks for any help in advance Jasvinder
