Multi-GGS Groups have the Congruence Subgroup Property
Multi-GGS Groups have the Congruence Subgroup Property
Abstract We generalize the result about the congruence subgroup property for GGS groups in [3] to the family of multi-GGS groups; that is, all multi-GGS groups except the one defined by the constant vector have the congruence subgroup property. New arguments are provided to produce this more general proof.
