Linux: How to allow group members to set/change permissions on a file

I thought I had a good understanding of how permissions worked on linux.

I have folder where it and everything inside has the owner "me" and the group "group". I gave the group rwx access on all the files and still members of the group cannot modify permissions on any files.

I'm using Redhat Enterprise Linux 5

Is it possible to allow group members to modify permissions on file and not just the owner? How?

Thanks in advance

Answer

No. Only the owner and root can change the permissions of a file or directory in *nix.
