All,
A “triadic relation” (or “ternary relation”) is a special case of a polyadic or
finitary relation, one in which the number of places in the relation is three.
One may also see the adjectives 3-adic, 3-ary, 3-dimensional, or 3-place being
used to describe these relations.
Mathematics is positively rife with examples of triadic relations
and the field of semiotics is rich in its harvest of sign relations,
which are special cases of triadic relations. In either subject, as
Peirce observes, the multitude of forms is truly terrific, so it's best
to begin with concrete examples just complex enough to illustrate the
distinctive features of each type. The discussion to follow takes up
a pair of simple but instructive examples from each of the realms of
mathematics and semiotics.
