  We study a nonminimal derivative inflationary model in the presence of the
Gauss-Bonnet term. To have a complete treatment of the model, we consider a
general form of the nonminimal derivative function and also the Gauss-Bonnet
coupling term. By following the ADM formalism, expanding the action up to the
third order in the perturbations and using the correlation functions, we study
the perturbation and its non-Gaussian feature in details. We also study the
consistency relation that gets modified in the presence of the Gauss-Bonnet
term in the action. We compare the results of our consideration in
confrontation with Planck2015 observational data and find some constraints on
the model's parameters. Our treatment shows that this model in some ranges of
the parameters is consistent with the observational data. Also, in some ranges
of model's parameters, the model predicts blue-tilted power spectrum. Finally,
we show that nonminimal derivative model in the presence of the GB term has
capability to have large non-Gaussianity.
