<snip>
      A  numeric  mode  is  from  one  to four octal digits (0-7), derived by
      adding up the bits with values 4, 2, and 1.  Any  omitted  digits  are
      assumed  to  be leading zeros.  The first digit selects the set user ID
      (4) and set group ID (2) and sticky (1) attributes.  The  second  digit
      selects  permissions  for  the  user who owns the file: read (4), write
      (2), and execute (1); the third selects permissions for other users  in
      the  file's group, with the same values; and the fourth for other users
      not in the file's group, with the same values.
