| Suppose R c XxYxZ is an arbitrary triadic relation and consider the information about R that is provided by collecting its dyadic projections. To formalize this information define the "projective triple" of R as follows: | | Suppose R c XxYxZ is an arbitrary triadic relation and consider the information about R that is provided by collecting its dyadic projections.
