\((s,r;\mu )\)-nets and alternating forms graphs
The authors extend the well-known equivalence between Bruck nets and mutually orthogonal Latin squares to \((s,r;\mu)\)-nets and mutually orthogonal quasi-frequency squares. They then study geometries arising from bilinear forms, alternating bilinear forms, hermitian forms, and symmetric forms and exhibit Buekenhout diagrams for these geometries involving the diagram for the duals of \((s,r;\mu)\)-nets. Finally, the local structure of the alternating forms graph is studied in some detail.
