Additional notes

The negation closure of this diagram is a classical sigma-2 diagram.

The two vertices of this diagram are subcontrary to each other; cf. "Indefinitè oppositae sunt, quae non habent notam quantitatis additam ... In materia verò contingente aequivalent duabus subcontrariis" (p. 52).
