Title: Finiteness property of subgroups of the symmetric group on Z

Abstract: Consider subgroups of the symmetric group on Z consisting of eventually periodic maps. In this talk we study their finiteness properties. We show that each of those groups has type F_{n-1} but not F_n for some positive integer n. We also show that this class of groups contains Houghton's groups.
