P. Fima correctly pointed out that, in the proof of the genericity of O 2 in the proof of Proposition 4 appeared in [Moo], the permutation σ ′ is a priori not well defined.This can be easily corrected if we can assume the Følner sequences in question to be A-invariant.The following lemma allows us to make this assumption:
