Consider the following list ``` list={0 < x < 1/12, 0 < x < 1/4} ``` I wish to find the intersection of the two ranges of `x` and check if the result is an element of the above list, i.e. ``` In:=Simplify[And @@ list] out:=0<x<1/12 ``` Now I want to check if the above range of `x` belongs to the `list`. ``` in:=MemberQ[list, Simplify[And @@ list]] out:= False ``` But It is clear that such a range is an element of `list`. This is not giving the expected result because the Heads are not matching. ``` in:=FullForm[Simplify[And @@ list]] out:=Inequality[0,Less,x,Less,Rational[1,12]] ``` Whereas, ``` in:=FullForm[0 < x < 1/12] out:=Less[0,x,Rational[1,12]] ``` How to resolve this?
