摘要:
An exact (λ,t)‐covering,B, of av‐setX, is a collection of proper subsets ofX, with the property that eacht‐subset ofXis contained in exactly λ members ofB. Letg(λ,t, v) denote the minimum cardinality |B| of an exact (λ,t)‐covering ofX. We show that ifq⩾ 3 is a prime power theng(1, 3,q2+ 1) =q3+q, the minimal configuration being an inversive plane. We also show thatg(1, 3,q2− α) =q3+qforq⩾ 4 and α 0, where α is small relative toq. A few isolated values ofg(1,t, v) fort>3 are also obtained.
