In this paper, we introduce a new encoding for a given binary relation, by using adjacency matrix constructed on the relation. Therefore, a coatom o f a concept lattice can be characterized by supports of row vectors of adjacency matrix. Moreover, we are able to compute a poly-sized sub-relation resulting in a sublattice of the original lattice for a given binary relation.
