Description: "Camestros", one of the syllogisms of Aristotelian logic. All ph is
ps , no ch is ps , and ch exist, therefore some ch
is not ph . In Aristotelian notation, AEO-2: PaM and SeM therefore
SoP. For example, "All horses have hooves", "No humans have hooves", and
humans exist, therefore "Some humans are not horses". (Contributed by David A. Wheeler, 28-Aug-2016) Reduce dependencies on axioms.
