Wild card in find perm

Hi,
Is there a way to use find command to list the directories for certain permissions. I know we can use

find . -type d -perm nnn

, where nnn is the permission number . However I wold like to know if I wanna search for wild card permissions i.e 75* / 7* / 55* , as i do not know the actual permission but i know a part of it.

So is it possible to do with 'find' command ?

Appreciate any inputs
Brian

find . -type d -perm -nnn

for the three examples you gave:

find . -type d -perm -750 
find . -type d -perm -700 
find . -type d -perm -550
