Theoretical predictions indicate that the shell gaps comparable or even stronger than those of the spherical shape may exist in nuclear systems. Group-theoretical analysis supported by realistic mean-field calculations point out that some rare-earth as well as actinide nuclei
can be characterized by the tetrahedral $T_d$ symmetry group.
Recently, the problem of existing high rank symmetries in atomic nuclei has become also a big challenge for experimental teams as a possible test of more and more sophisticated facilities.
This work, in fact is tightly connected to the two recent experiments for $^{156}$Gd and $^{156}$Dy nuclei carried out in the ANL and ILL laboratories. Their results reveal totally opposite behavior of these two isobars with respect to the ''tetrahedral scheme''.
Using well established GCM+GOA and TDHF microscopic approaches on top of the realistic mean-field spectra we attempt to refer to the results of both these experiments.
