Abstract
If is a Grigorchuk–Gupta–Sidki group defined over a -adic tree, where is an odd prime, we study the existence of Beauville surfaces associated to the quotients of by its level stabilizers . We prove that if is periodic then the quotients are Beauville groups for every if and if . In this case, we further show that all but finitely many quotients of are Beauville groups. On the other hand, if is non-periodic, then none of the quotients are Beauville groups.
