A D-dimensional gravitational model with Gauss-Bonnet and cosmological term
is considered. When ansatz with diagonal cosmological metrics is adopted, we
overview recent solutions for zero cosmological term and find new examples of
solutions for non-zero cosmological term and D = 8 with exponential dependence
of scale factors which describe an expansion of our 3-dimensional factor-space
and contraction of 4-dimensional internal space.Comment: 7 pages, Latex, no figures. To be published in: Proceedings of the
