A superhalogen F@C20(CN)20 and a corresponding Br{\o}nsted superacid were designed and investigated on DFT and DLPNO-CCSD(T) levels of theory. Calculated compounds have outstanding electron affinity and deprotonation energy, respectively. We consider superacid H[F@C20(CN)20] to be able to protonate molecular nitrogen. The stability of these structures is discussed, while some of the previous predictions concerning Br{\o}nsted superacids of record strength are doubted.
