In this paper we investigate the strong gravitational lensing with Gauss-Bonnet gravity. By considering the logarithmic term for deflection angle, we obtain the deflection angle α^ and corresponding parameters aˉ and bˉ. Finally, by using the relations between the observables and lensing parameters, we estimate the observables such as, θ∞, s and rm, for the relativistic images in the Gauss-Bonnet background.
