AbstractLet |S|=n. The numbers m(n, k)=|{(S1,…,Sk):∪ Si=S and, ∀t∈[1,k], ∪i≠lSi≠S| have been studied previously by Hearne and Wagner. The present paper treats three arrays, m̄(n,k), m̄(n,k), and m̂(n,k), which extend m(n,k) in the sense that m̂(p1⋯ps,k)=m̄(p1⋯ps,k)=m̂(p1⋯ps,k)=m(s,k) for all sequences (p1,…ps) of distinct primes
