Abstract
Symmetry plays a key role in identifying the close connection between different finite incidence structures. In this paper, by studying the properties of points not belonging to an elliptic quadric of PG(3,3), a short demonstration is given of the close connection between the Steiner Quadruple system SQS(10) and the Cremona–Richmond configuration.File in questo prodotto:
