....most j n(n Gamma1) 3 k hyperedges. Equality occurs when all, or all but one, pair of vertices occur in two hyperedges each. Chee, Colbourn, and Ling [6] establish that equality is met for all n j 0; 1 (mod 3) with a small number of definite, and a small number of possible, exceptions. Denny [7] eliminated the possible exception when n = 12 by computational search. Theorem 1.2. A wuf TTS(n) exists whenever n j 0; 1 (mod 3) except when n 2 f3; 4; 6; 7; 9; 10; 12g and possibly when n 2 f15; 18; 22g. Weakly Union free Maximum Packings 3 Theorem 1.1 also admits the possibility that n j 2 ....
