Direct constructions of some group divisible designs with block size $4$ and up to $50$ points

R. Julian. R. Abel, Thomas Britz, Yudhistira A. Bunjamin +1

In this note, we give direct constructions of some group divisible designs (GDDs) with block size $4$ that have up to $50$ points.

Group divisible designs with block size 4 and group sizes 4 and 7

R. Julian R. Abel, Thomas Britz, Yudhistira A. Bunjamin +1

In this paper, we consider the existence of group divisible designs (GDDs) with block size $4$ and group sizes $4$ and $7$ . We show that there exists a 4-GDD of type $4^{t} 7^{s}$ for…

Group divisible designs with block size 4 and group sizes 2 and 5

R. Julian R. Abel, Thomas Britz, Yudhistira A. Bunjamin +1

In this paper we provide a $4$ -GDD of type $2^{2} 5^{5}$ , thereby solving the existence question for the last remaining feasible type for a $4$ -GDD with no more than $30$ points. We th…
