Hello, I am trying to contruct strongly regular graphs (SRGs) from generalized quadrangles of order (5,5^2). There are 2 known non-isomorphic generalized quadrangles of this family. I can construct one using t = designs.generalised_quadrangle_hermitian_with_ovoid(5) and the corresponding SRG using G = t[0].intersection_graph([1]).

Is there a way to obtain the other?
