  We use an elementary argument building on group actions to prove that the
selection-free steady state genetic algorithm analyzed by Sutton and Witt
(GECCO 2019) takes an expected number of $\Omega(2^n / \sqrt n)$ iterations to
find any particular target search point. This bound is valid for all population
sizes $\mu$. Our result improves over the previous lower bound of
$\Omega(\exp(n^{\delta/2}))$ valid for population sizes $\mu = O(n^{1/2 -
\delta})$, $0 < \delta < 1/2$.
