Additional notes
- The vertices contain de dicto quantified modal statements. I and II stand for a universal and existential quantifier, respectively.
Examples:
$\circ$ Purpurea I = it is necessary that all S are P
$\circ$ Purpurea II = it is necessary that some S are P
$\circ$ Amabimus I = it is possible that all S are P
$\circ$ Amabimus II = it is possible that some S are P
