I want a way to map natural numbers to possible values of set A. It would also be helpful if you could tell me how many possible values are for set A(it depends of k).
All that is known about set A is: Non of set A elements is subset to another element of A, but all elements of set A are proper subsets to set B. Empty set is not element of A. Set B contains k elements.
example if k=1

- A={}
- A={}
- A={{0}}
- A={{1}}
- A={{0}{1}}
- A={}
- A={{0}}
- A={{1}}
- A={{2}}
- A={{0},{1}}
- A={{0},{2}}
- A={{1},{2}}
- A={{0},{1},{2}}
- A={{0,1}}
- A={{0,1},{2}}
- A={{0,2}}
- A={{0,2},{1}}
- A={{1,2}}
- A={{1,2},{0}}
- A={{0,1},{0,2}}
- A={{0,1}{1,2}}
- A={{0,2}{1,2}}
- A={{0,1},{0,2},{1,2}}
