Any kind of ballot that is more expressive than lone mark plurality could
be used.  Each row of the starting matrix represents one ballot with the
ballot marks, whether grades, yes, no, ranks, ratings, etc. all encoded

Note that approval ballots don't fully order the candidates, but (given
more than two factions) the point X in the row space of A will almost
surely have as many distinct entries as there are candidates, because of
the the rotations, etc.
