Arrays with three different ratios $\\gamma =a/b = \\sqrt{2}$, $\\sqrt{3}$ and $\\sqrt{4}$ are studied. Theoretical calculations of low-energy demagnetized configurations for these same parameters are also presented. Experimental data for demagnetized samples confirm most of the theoretical results.
