Abstract
Generalizations of Einstein's field equations in general relativity are derived by considering variational principles in which the components of an ennuple, or tetrad, are the quantities which undergo variation. The conservation law for the field equations is established and the weak field approximations discussed. The equations are solved by the method developed in a previous article (abstr. A32263 of 1970). Many solutions are obtained, all of which are inferior to the Schwarzschild solution.
