Abstract In this paper it is shown that a regular group divisible (GD) design, with parametersv, b, r, k, λ 1, λ2 satisfyingrk − λ2 v + 1 andλ 2 = λ1 + 1, must be symmetric (i.e.,v + b). Furthermore, the parameters of such symmetric regular GD designs can be expressed in terms of only two integral parameters.
