We prove that if G
is a Polish group and A
a group admitting a system of generators whose associated length function satisfies: (i) if
; (ii) if
, then there exists a subgroup
(the bounding number) such that
is not embeddable in A
. In particular, we prove that the automorphism group of a countable structure cannot be an uncountable right-angled Artin group. This generalizes analogous results for free and free abelian uncountable groups.
