A t-(n,k,λ;q)t-(n,k,λ;q)-design is a set of k -dimensional subspaces, called blocks, of an n -dimensional vector space V over the finite field with q elements such that each t -dimensional subspace is contained in exactly λ blocks. A partition of the complete set of k -dimensional subspaces of V into disjoint t-(n,k,λ;q)t-(n,k,λ;q) designs is called a large set of t -designs over finite fields. In this paper we give the first nontrivial construction of such a large set with t⩾2t⩾2.
