This study is carried out in the context of $ (L, M) $-fuzzy weak hull operators. First, we introduce the concept of an $ (L, M) $-fuzzy quasi-hull operator and prove that $ (L, M) $-fuzzy quasi-hull operators are categorically isomorphic to $ (L, M) $-fuzzy supratopologies. Second, by imposing a compatibility condition with group structures, we propose the notion of an $ (L, M) $-fuzzy weak hull group and further investigate its relevant properties, such as those related to its subgroups and product groups.
