This doesn't capture the case where:

  • the chemist mole and the zoologist mole and the government mole are all valid, but the dermatologist one isn't

Or the case where

  • the chemist mole and the zoologist mole and the dermatologist mole are all valid, but the government one isn't
  • the chemist mole and the government mole and the dermatologist mole are all valid, but the zoologist one isn't
  • the government mole and the zoologist mole and the dermatologist mole are all valid, but the chemist one isn't

If you make a Venn Diagram from circles, for every circle above 3 you need to increase the number of dimensions of the circles AND the domain-space (the paper it is drawn on) by 1.

    I feel like I'm missing something, because it looks like it covers all of these:

    • "southwest" of center,
    • "northeast" of center,
    • "northwest" of center, and
    • "southeast" of center, respectively.

    What it doesn't capture is chemist & zoologist only and government & dermatologist only. (4c4 is 1, covered; 4c3 is 4, all covered, and 4c1 is obviously 4, also covered, but 4c2 is 6, and only 4 are covered.)
