A sporadic strongly regular graph with parameters $(120, 56, 28, 24)$ from a primitive action of the symmetric group on $7$ elements

Sam Adriaensen, Robert F. Bailey, Jan De Beule +1

There are up to isomorphism exactly three strongly regular graphs with parameters $(120, 56, 28, 24)$ whose automorphism group acts primitively on the vertices. Two of these graphs be…

Regular sets of lines in rank 3 polar spaces

Ferdinand Ihringer, Morgan Rodgers

There are 6 families of finite polar spaces of rank $3$ . The set of lines in a rank $3$ polar space form a rank $5$ association scheme. We determine the regular sets of minimal siz…
