IIRC The descriptions of the traditional permissions "-rw-rw-rw" are 
world(others), group, and user - in that order - reading from left to 
right. For executables and if the "-" is replaced with an "x", the 
file can be executed.

Again IIRC, for directories(folders) and if the "-" is replaced with 
an "x", the directory can be traversed, i.e. can be an intermediate 
directory in a path to another directory which has both "x" and "r" 
attributes.

As I am unfamiliar with the sticky bit, the setgid bit and with ACL, 
I am following this thread closely.
