It is known that any compact connected Lie group with its left invariant framing is framed null-cobordant in the -component for any prime . In this paper we will prove that the 3-components of and are zero for , . Combining this with the previously known results on and consequently we see that any classical group has at most only the 2-component with some exceptions.
