Abstract:
Abstract The construction of Bays and deWeck [1] of a Steiner Quadruple System SQS(14) was generalized by Piotrowski in his dissertation ([7], p. 34) to an SQS(2p), p ≡ 7 mod 12 with a group transitive on the points. However he gave no proof of his construction and his presesntation was open to misinterpretation. So Hanfried Lenz suggested to analyse Piotrowski’s construction and to supply it with a proof. In the following we will present Piotrowski’s ideas somewhat differently and will furnish a proof of the construction.
