  $\Gamma$-symmetric spaces are a vast generalization of symmetric spaces.
Previous results make it conceivable that their isotropy action is
equivariantly formal, and we provide evidence for this in case that $\Gamma =
\mathbb{Z}_2\times\mathbb{Z}_k$. This in particular implies that
$\mathbb{Z}_2\times\mathbb{Z}_k$-symmetric spaces are formal in the sense of
Rational Homotopy Theory.
