Given graphs H1, . . . , Hk, let f(H1, . . . , Hk) be the minimum order of a graph G such that for each i, the induced copies of Hi in G cover V(G) We prove constructively that f(H1, H2) ≤ 2(n(H1) + n(H2) - 2); equality holds when H1 = H̄2 = Kn. We prove that f(H1,K̄n) = n + 2√δ(H1)n + O(1) as n → ∞. We also determine f(K1,m - 1,K̄n) exactly.
