We consider Maxwell and Yang-Mills (YM) fields together, interacting through gravity both in Einstein and in Gauss-Bonnet (GB) theories. For this purpose we choose two different sets of Maxwell and metric ansaetze. In our first ansatz, asymptotically for r {yields} 0 (and N > 4) the Maxwell field dominates over the YM field. In the other asymptotic region, r {yields} {infinity}, however, the YM field becomes dominant. For N = 3 and 4, where the GB term is absent, we recover the well-known Banados-Teitelboim-Zanelli and Reissner-Nordstroem metrics, respectively. The second ansatz corresponds to the case of constant radius function for the S{sup N-2} part in the metric. This leads to the maximally symmetrical, everywhere regular, Bertotti-Robinson type of solutions for representing our cosmos both at large and small scales.
