Let (v, u × c,λ)-splitting BIBD denote a (v, u × c,λ)-splitting balanced incomplete block design of order v with block size u × c and index A. The necessary conditions for the existence of a (v, u × c,λ)-splitting BIBD are v ≥ uc, λ(v- 1) -- 0 0 mod (c(u- 1)) and Av(v- 1) - 0 mod (c^2u(u- 1)). In this paper, for 2 ≤λ≤ 9 the necessary conditions for the existence of a (v, 3 × 3, λ)-splitting BIBD are also sufficient with one possible exception for (v, λ) = (39, 9).
