## Abstract

We consider a $(7 + k)$-dimensional Einstein-Gauss-Bonnet model with the cosmological $\\Lambda$-term. A cosmological model with three factor spaces of dimensions $3$, $3$ and $k$, $k \> 2$ is considered. Exact stable solutions with three (non-coinciding) Hubble-like parameters in this model are obtained. Some examples of solutions (e.g. with zero variation of the effective gravitational constant $G$) are considered in selected dimensions (for $k = 5, 6$).

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
