Triadic Relation
1899 | On Topical Geometry, in General (T) | CP 7.537

It is impossible to analyze a triadic relation, or fact about three objects, into dyadic relations; for the very idea of a compound supposes two parts, at least, and a whole, or three objects, at least, in all. On the other hand, every tetradic relation, or fact about four objects can be analyzed into a compound of triadic relations.

1905-07 [c.] | Considerations concerning the Doctrine of Multitude | MS [R] 27:5

A triadic relation is a general relation of triads, or ordered triplets. [—] A genuine triadic relation is one which neither consists of dyadic relations nor of monadic characters.
