Query: Strong Gravitational Lensing with Gauss-Bonnet correction   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 $\hat\alpha$ and corresponding parameters
$\bar{a}$ and $\bar{b}$. Finally, by using the relations between the
observables and lensing parameters, we estimate the observables such as,
$\theta_{\infty}$, $s$ and $r_m$, for the relativistic images in the
Gauss-Bonnet background.
