On a locally compact group G, if\(v_n^{k_n } \to \mu ,(k_n \to \infty )\), for some probability measuresvn and μ onG, then a sufficient condition is obtained for the set\(A = \{ v_n^m \left| {m \leqslant k_n } \right.\} \) to be relatively compact; this in turn implies the embeddability of a shift of μ. The condition turns out to be also necessary when G is totally disconnected. In particular, it is shown that ifG is a discrete linear group over R then a shift of the limit μ is embeddable. It is also shown that any infinitesimally divisible measure on a connected nilpotent real algebraic group is embeddable.
