  In this article we prove some interesting results on field generated by
division points of several formal groups of same height, already implicit in
the treatment in appendix-A of my M.Sc thesis (Points of Small Height in
Certain Nonabelian Extensions). More precisely, under suitable hypothesis we
show that the field generated by the division points of several formal groups
is equal to the field generated by division points of an individual formal
group among them, after a fixed finite unramified extension of base field.
