ab: Summary: Finding classes of digraphs whose adjacency matrices have equal
    $\{0,1\}$-matrix ranks has been approached from several different
    angles. In this paper, we look at the real, Boolean, nonnegative
    integer and term ranks of adjacency matrices of local out-tournaments.
    A local out-tournament is a digraph where the outset of every vertex is
    a tournament. We explore constructions where all ranks are equal and
    the matrix is nonsingular.
