Abstract
We consider the relation between geometrically finite groups and their limit sets in infinite-dimensional hyperbolic space. Specifically, we show that a rigidity theorem of Susskind and Swarup (Am J Math 114(2):233–250, 1992) generalizes to infinite dimensions, while a stronger rigidity theorem of Yang and Jiang (Bull Aust Math Soc 82(1):1–9, 2010) does not.

Notes
We call two groups \(G_1\) and \(G_2\) commensurable if the group \(G_1\cap G_2\) has finite index in both \(G_1\) and \(G_2\).
I.e. a set for which each left coset \(g G_1\) of \(G_1\) intersects \(T\) exactly once.
A group \(\Gamma \) is said to act sharply transitively on a set \(V\) if for all \(v,w\in V\), there exists a unique element \(\gamma \in \Gamma \) such that \(\gamma (v) = w\).
