The infinitude conjecture for cyclic groups with the weak acyclic matching property

About 2 years old · traced to

Following Aliabadi, an abelian group GG has the weak acyclic matching property if, for every pair of finite nonempty subsets A,B⊆GA,B\subseteq G with ∣A∣=∣B∣|A|=|B| and A∩(A+B)=∅A\cap(A+B)=\emptyset, the set AA is acyclically matched to BB. Here Z/nZ\mathbb{Z}/n\mathbb{Z} denotes the cyclic group of order nn. Infinitude conjecture. There are infinitely many nn for which Z/nZ\mathbb{Z}/n\mathbb{Z} has the weak acyclic matching property. The conjecture asks whether this property occurs for infinitely many finite cyclic groups; its resolution is not indicated in the supplied source context.
