Would someone be able to explain to me how we would find antichains and chains of a powerset?

For example, if we had the power set of 4 - P([4]) then how would we derive the antichains, and symmetric chains?

What about for the power set of [5]? (where [5] is the set of numbers {1,2,3,4,5}.

Is there are a general formula to follow or simply a trial and error method?
