Query: Polarised Lie groups contactomorphic to stratified groups   For a stratified group $G$, we construct a class of polarised Lie groups,
which we call modifications of $G$, that are locally contactomorphic to it.
Vice versa, we show that if a polarised group is locally contactomorphic to a
stratified group $G$, whose Lie algebra has finite Tanaka prolongation, then it
must be a modification of $G$.
