COMMENTS
A relation R is limit dominating iff R converges to a single limit L (A365534) and R contains L. See Gregory, Kirkland, and Pullman.
A convergent relation R is limit dominating iff the following implication holds for all x,y in [n]. If there is a cyclic traverse from x to y in G(R) then (x,y) is in R, where G(R) is the directed graph with loops associated to R.
A relation R is limit dominating iff it converges to L, the biggest dense relation (A355730) contained in R. In which case L is the intersection of R^i for all i>=1. - Geoffrey Critzer, Dec 03 2023
