## A construction is given for a (pzO(p+ 1),p2,pZnf'(p+ l),~?"+',p~~(p+ 1)) (p a prime) divisible difference set in the group H x 2, \*a+ I where His any abelian group of order pf 1. This can be used to generate a symmetric semi-regular divisible design; this is a new set of parameters for A, #O,
## Abstract We present two direct productβtype constructions which will prove useful in the construction of resolvable designs. We use our constructions to complete the spectrum for resolvable groupβdivisible designs with block size three, as well as to give a short proof of the existence of decomp
