's' is the 'sticky' bit.  It has various uses depending on which position
it appears in.  If it's in the owner permissions, it's a SUID program--that
means that, when run, it gets run with the UID (user ID) of the owner of
the file.  A similar effect holds for the group ID--GID.

A 'man ls' will probably tell more and in a more comprehensable fashon.
