| Popis: | In this paper we investigate the strong gravitational lansing in a charged squashed Kaluza-Klein G\"{o}del black hole. The deflection angle is considered by the logarithmic term proposed by Bozza et al. Then we study the variation of deflection angle and its parameters $\bar{a}$ and $\bar{b}$ . We suppose that the supermassive black hole in the galaxy center can be considered by a charged squashed Kaluza-Klein black hole in a G\"{o}del background and by relation between lensing parameters and observables, we estimate the observables for different values of charge, extra dimension and G\"{o}del parameters.
