Group divisible designs with large block sizes

Designs, Codes and Cryptography, 2017
In this paper, the author showed that there is a \((k,\lambda_k)\)-GDD, group divisible design, of type \((q^{l+1}-q^l)^{(q^{n-l}-1)/(q-1)}\), for any prime power \(q\) and any integers \(k\), \(n\) with \(3\leq k \leq n\), where \(\lambda_k=\frac{\prod_{i=3}^{k-1}(q^n-q^{l+i-1})}{(k-2)!}\) and \(k+l\leq n+1\).

Matrix constructions of family (A) group divisible designs [PDF]

Australas. J Comb., 1995
A new construction of (not necessarily symmetric) group divisible designs (GDD) with \(b= 4(r- \lambda_2)\) is described (\(b\) denotes the number of blocks of the design, and \(\lambda_2\) the number of blocks through two points in different point classes; \(r\) is the number of blocks through a point). GDDs with this property are called ``family (A)''
