Abstract
Necessary and sufficient conditions for the existence of Group divisible designs with two groups of unequal sizes and block size tree with λ2 = 3, λ1 ≥ 3 are here considered. We find that the necessary conditions, derived from graph theoretic conditions, are sufficient as well. We present some constructions to prove sufficiency.
