584	Combination error	Jorge Conde	Christian Paz	"The ""Combination"" function returns a wrong object when the second argument is 1. 

Example:
Set a = Range(1,3,1);
Set b = EvalSet(a, Set(Real r){
  Combination(a, r)
});

Should return b as a set with three sets. The first with three elements (combinations of three elements taken one by one), the second with three (combs of three taken in groups of two), and the third with one (combs of three taken in groups of three).
The first one fails, returnig the same element as the third!"	defect	closed	highest		SetAlgebra	head	blocker	fixed
