A fun consequence of this is that in the group Sym(Z) of permutations of the integers, the two permutations: (0 1) and x --> 1 + x together generate a (finitely-generated!) group G which contains, as a subgroup, the group of all finitely-supported permutations (which is definitely not finitely-generated).

The entire perm group S[n] is generated by the n-cycle (1,2,3,...,n) and the transposition (1,2), not sure if that suffices to make Baker happy.
