By combining the two- and three-point statistics, we are able to partially break the degeneracy between the logarithmic growth rate, $f(z)$, and the amplitude of dark matter fluctuations, $\\sigma_\\textrm{s8}(z)$, which cannot be measured separately in analyses that only involve the power spectrum.
