Jan 17	comment	Direct formula for elements of power set? That's one possible ordering, true. Using that particular order then you should be able to work out the formula pretty quickly. F[0] = empty_set, F[3] = {3}, F[n+2]={1,2}, etc. Some clever modular arithmetic might give you the right answer in this particular case.
