  abstract =     "We present three different techniques that use
                 information about symmetries detected in the input
                 formula to block the expansion of diamonds in a modal
                 tableau. We show how these blocking techniques can be
                 included in a standard tableaux calculus for the basic
                 modal logic, and prove that they preserve soundness and
                 completeness. We empirically evaluate these blocking
                 mechanisms in different modal benchmarks.",
