  We deal with Einstein-Gauss-Bonnet model in dimension $D$ with a
$\Lambda$-term. We obtain three stable cosmological solutions with exponential
behavior (in time) of three scale factors corresponding to subspaces of
dimensions $(l_0,l_1,l_2) = (3, 4, 4), (3, 3, 2), (3, 4, 3)$ and $D = 12, 9,
11$, respectively. Any solution may describe an exponential expansion of
$3$-dimensional subspace governed by Hubble parameter $H$. Two of them may also
describe a small enough variation of the effective gravitational constant $G$
(in Jordan frame) for certain values of $\Lambda$.
