In economics or other fields, there's a concept trilemma. It means
A trilemma is a difficult choice from three options, each of which is (or appears) unacceptable or unfavourable. There are two logically equivalent ways in which to express a trilemma: it can be expressed as a choice among three unfavourable options, one of which must be chosen, or as a choice among three favourable options, only two of which are possible at the same time.
However, I have a new idea relevant to trilemma. Say there are three things A, B, C. If any two of them occur, the third must occur as well. That is to say:
A, B --> C C, B --> A A, C --> B
What I am going to ask is is there a concept in philosophy or logic to describe the relationship between A, B, and C I mentioned above?
