The connection between Einstein Gravity and the Euler characteristic is reviewed and a generalization is considered. In this way, a four dimensional action principle, gauge invariant under the conformal group, SO(4,2), is regarded as a possible generalization of Einstein theory. This theory is defined by a gauged Wess-Zumino-Witten form. The theory is briefly discussed and is shown how usual Einstein theory plus the cosmological constant term arise.
