    "abstract": "We study static non-axial octupole deformations in proton-rich $Z=N$ nuclei,\n$^{64}$Ge, $^{68}$Se, $^{72}$Kr, $^{76}$Sr, $^{80}$Zr and $^{84}$Mo, by using\nthe Skyrme Hartree-Fock plus BCS calculation with no restrictions on the\nnuclear shape. The calculation predicts that the oblate ground state in\n$^{68}$Se is extremely soft for the $Y_{33}$ triangular deformation, and that\nin $^{80}$Zr the low-lying local minimum state coexisting with the prolate\nground state has the $Y_{32}$ tetrahedral deformation.",
