The only thing I would add is the set user, set group, and sticky bit.

Add the numbers generated above to the following:

4000 set-user-ID-on-execution
2000 set-group-ID-on-execution
1000 sticky bit

Set user changes the effective UID to the owner of the file.

Set group changes the effective GID to the owner of the file.

Sticky bit used on a directory allows users to write files in that directory. an example of a sticky bit directory would be /tmp
