In this paper, by means of the same methods, we show that any anisotropy of nearest-neighbor hopping eliminates the $π/2$-rotation degeneracy of the so called dimeric and axial-stripe phases and orients them in the direction of a weaker hopping. Moreover, due to the same anisotropy the obtained phase diagrams of fermions show a tendency to become similar to those of hardcore bosons.41 pages, 17 figures, 28 tablesStrongly Correlated ElectronsStatistical Mechanicstext
