Finiteness conjecture for the V-like Lodha–Moore group

From papers

Let GG be the Lodha–Moore group and let

V(G)=V,GHomeo({0,1}N).V(G)=\langle V,G\rangle\leq \operatorname{Homeo}(\{0,1\}^{\mathbb{N}}).

Its commutator subgroup is [V(G),V(G)][V(G),V(G)].

Finiteness conjecture. The group V(G)V(G) and its commutator subgroup [V(G),V(G)][V(G),V(G)] are of type F\operatorname{F}_\infty.

The group V(G)V(G) is finitely generated, and its commutator subgroup is simple. The methods used in the paper for the analogous groups S^\widehat{S} and SS do not establish this conjecture, so the finiteness properties of V(G)V(G) and [V(G),V(G)][V(G),V(G)] remain open.
