It is surveyed the area of strongly regular graphs satisfying the \(4\)-vertex condition and are obtained several new families. It is described a switching operation on collinearity graphs graphs of polar spaces that produces cospectral graphs. The obtained graphs satisfy the \(4\)-vertex condition if the original graph belongs to a symplectic polar space.
