Abstract
We present a graphical representation that allows us to easily determine if a certain modal function is or is not a polymorphism of a given relation. While doing so, we provide a comparison between two ways (a calculative and a diagrammatic one) to analyze a claim about the Sheferness criterion in the theory of clones of (S5) modal functions.
