Binary adjacency matrix
Web6. Given any square, symmetric, binary matrix Q of order n, one can always construct a graph G of n vertices (and no parallel edges) such that Q is the adjacency matrix of G. Powers of X: Multiply by itself the 6 by 6 adjacency matrix of the simple graph. The result, another 6 by 6 symmetric matrix X 2 , WebDec 7, 2015 · $\begingroup$ Since you are looking at a a matrix representation of the relation, an easy way to check transitivity is to square the matrix. The relation is transitive if and only if the squared matrix has no nonzero entry where the original had a zero. (If you don't know this fact, it is a useful exercise to show it.) $\endgroup$

Otherwise, A is said to be irreducible.
