HoheiselMathematisches Institut B Universität Stuttgart 70550 Stuttgart Germany stroppel@mathematik.uni-stuttgart.de Abstract: Heisenberg groups are simply connected nilpotent Lie groups of class $2$. A group is called almost homogeneous if its automorphism group acts with at most $3$ orbits. Several open problems about the existence of embeddings between almost homogeneous Heisenberg groups have been posed in a previous paper by the second author. Most of these problems are solved.
