This definition gives a generalization of both right delta-semiperfect rings and right generalized semiperfect rings. We provide examples involving such rings along with some of their properties. We introduce flat strong delta-cover of a module as a flat cover which is also a flat delta-cover and use flat strong delta-covers in characterizing right A-perfect rings, right B-perfect rings and right perfect rings.eninfo:eu-repo/semantics/openAccessFlat coverflat delta-coverflat strong delta-coverG-delta-semiperfect ringsemiperfect ringperfect ringArticle681435210.31801/cfsuasmas.443540N/A377500WOS:000463698900004N/A
