The obtained symmetries and Erde� lyi�Kober fractional differential operator are used to reduce the original nonlinear partial differential equation into nonlinear ordinary differential equation. The generalized Noether operator and new conservation theorem are exploited to obtain conservation laws of the governing equation. The power series solution is also derived for the considered equation. The obtained power series solution is investigated for the convergence and the obtained power series solution is convergent. � 2021, The Author(s), under exclusive licence to Islamic Azad University.en-USCaudrey�Dodd�Gibbon�Sawada�Kotera equationConservation lawsErde� lyi�Kober fractional differential operatorPower series solutionRiemann�Liouville fractional differential operatorSymmetry reductionArticlehttps://link.springer.com/10.1007/s40096-021-00443-z
