Antagonistic symmetries of superconducting polygons and their inducedmulti-vortex states in a homogeneous magnetic field may lead to appearance ofantivortices in the vicinity of the superconducting/normal state boundary(where mesoscopic confinement is particularly strong). Resultingvortex-antivortex (V-Av) molecules match the sample symmetry, but are extremelysensitive to defects and fluctuations and remain undetected experimentally.Here we show that V-Av states can re-appear deep in the superconducting statedue to an array of perforations in a polygonal setting, surrounding a centralhole. Such states are no longer caused by the symmetry of the sample but ratherby pinning itself, which prevents the vortex-antivortex annihilation. As aresult, even micron-size, clearly spaced V-Av molecules can be stabilized inlarge mesoscopic samples.
