We consider recently proposed higher order gravity models where the action isbuilt from the Einstein-Hilbert action plus a function f(G) of the Gauss-Bonnetinvariant. The models were previously shown to pass physical acceptabilityconditions as well as solar system tests. In this paper, we compare the modelsto combined data sets of supernovae, baryon acoustic oscillations, andconstraints from the CMB surface of last scattering. We find that the modelsprovide fits to the data that are close to those of the LCDM concordance model.The results provide a pool of higher order gravity models that pass these testsand need to be compared to constraints from large scale structure and full CMBanalysis.
