Let $G$ be a group acting faithfully on a set $S$, and let $SV_G$ be the associated twisted Brin–Thompson group. For $n\geq 1$, an action is of type $\operatorname{F}_n$ when the r…

Let $G$ be a group acting faithfully on a set $S$. The twisted Brin–Thompson group $SV_G$ is associated to this action. An action is said to have type (A) when $G$ is finitely pres…
