1984_03_01_frankl_furedi: Frankl and Füredi (1984) determine T(n,r) exactly for every fixed r and all n large in terms of r, with the extremal family unique; a partial answer to the problem's request for estimates.

1987_03_01_frankl_rodl: Frankl and Rödl (1987), Theorem 1.1: a family of subsets of an n-set with no two members meeting in exactly r points, for r between epsilon n and (1/2 minus epsilon) n, has fewer than (2 minus delta)^n members.
