Abstract :
The necessary and sufficient conditions for the existence of a ( 3 , 1 ) -GDD of type g t u 1 have been established by Colbourn et al. In this paper, the existence of a ( 3 , λ ) -GDD of type g t u 1 for any λ ≥ 2 is investigated. Finally, its existence spectrum is completely determined.
