Let l>k⩾3. Let the k-graph Hl(k)be obtained from the complete 2-graph Kl(2)by enlarging each edge with a new set of k−2 vertices. Mubayi [A hypergraph extension of Turánʼs theorem, J. Combin. Theory Ser. B 96 (2006) 122–134] computed asymptotically the Turán function ex(n,Hl(k)). Here we determine the exact value of ex(n,Hl(k)) for all sufficiently large n, settling a conjecture of Mubayi.
