Fifteen strongly oscillating angular distributions of the elastic scattering of {sup 12}C+{sup 24}Mg at energies around the Coulomb barrier (E{sub c.m.}=10.67-16.00 MeV) are reproduced by adding five Breit-Wigner resonance terms to the l=2,4,6,7, and 8 elastic S matrix. The nonresonant, background elastic scattering S matrix S{sub l}{sup 0} is calculated using the Sao Paulo potential. The J=2,4,6,7, and 8 ({Dirac_h}/2{pi}) molecular resonances fit well into a rotational molecular band, together with other higher lying resonances observed in the {sup 16}O+{sup 20}Ne elastic scattering. We propose that the presently observed, largely deformed molecular band corresponds to the hyperdeformed band, which has been found previously in {alpha}-cluster calculations, as well as in a new Nilsson model calculation. Systematic study of its possible clusterizations predicts the preference of the {sup 12}C+{sup 24}Mg and {sup 16}O+{sup 20}Ne molecular structure, in accordance with our present results.
