L.P. Einsenhart has defined in [1,2] a generalized Riemannian space with nonsymmetric basical tensor, R. S. Maishra and M. Prvanović in [3,4] have studied derivational formulas and Gauss-Codazzi equations in a subspace of a generalized Riemannian space. In [5,6] we used 4 kinds of covariant derivation of a tenzor in a sbspaces of this space. In the present work we obtain 4 kinds of derivational formulas, using the above mentioned kinds of derivation.
