By performing fully 3D symmetry-unrestricted Skyrme-Hartree-Fock-Bogoliubov calculations, we discuss shape coexistence and possibility of exotic defor mations simultaneously breaking the reflection and axial symmetries in prot on-rich N = Z nuclei: Ge-64, Se-68, Kr-72,Sr-76, Zr-80 and Mo-84. Results o f calculation indicate that the oblate ground state of Se-68 is extremely s oft against the Y-33 triangular deformation, and that the low-lying spheric al minimum coexisting with the prolate ground state in Zr-80 is extremely s oft against the Y-32 tetrahedral deformation.
