    Please see the attached file for the fully formatted problems.

    Let A = {a, b, c, d} and let the relation R be defined on A by the matrix

    MR = Note, take the nodes in A in the order given

    Use Warshall's Algorithm to determine the transitive closure of R.

    Draw the digraph of the transitive closure of R and use the digraph to explain the idea of connectivity. Is this graph connected? What does this mean?
