    Natural Language Statement

    Lemma

    At a component keep precisely the nominal primal rays belonging to incident selected atoms. Their span has dimension at most twenty-eight, is contained in the combined primal space, and is disjoint from every table space when the labels avoid the sparse exclusions.
