The letters `rwxXstugo' select the new permissions for the  affected
users: read (r), write (w), execute (or access for directories) (x),
execute only if the file is a directory or already has execute
per-mission  for  some  user (X), set user or group ID on execution
(s), save program text on swap device (t), the permissions that the
user who  owns  the  file  currently has for it (u), the permissions
that other users in the file's group have for it (g), and the
permissions that other users not in the file's group have for it (o).

This is from the chmod man page :)
For more info check out the man page or do an "info" on chmod.

Next time just do a: 

man -k permissions [or whatever]. 

This should point u in the right direction or round about.
