RactLattice.universes takes a 2D list of Universe. You could just do something like this,

RactLattice.universes = [ 
                          [universe_21, universe_22, universe_23],
                          [universe_11, universe_12, universe_13],
                          [universe_01, universe_02, universe_03]
                        ]
