I just asked today the following question: On groups with finite pro-$p$ completion for all primes $p$. However, I can actually simplified what I am interested in, but as it is somewhat a more general question I will leave both of them. I would like to know of examples of finitely generated groups for which it
It is unknowna famous open question whether theirevery finitely generated group without polynomial growth has word growth is bounded below by $e^{\sqrt{n}}$$\succeq e^{\sqrt{n}}$. In particularSo my question is:
Are there "known" finitely generated groups, not of polynomial growth, for which the growth is not known to be $\succeq e^{\sqrt{n}}$?
That is, agroups that are at least test candidates for the above open question. I am especially interested by residually finite such examples.
A result of Grigorchuk, see Theorem E.2 in https://arxiv.org/pdf/1512.07044.pdf, excludes many potential examples, e.
Edit: Actually I would like the examples to beg., residually-finite if possible nilpotent finitely generated groups.
