After a short read of "man ls":

"s" in the owner permissions = file is executable and set-user-ID mode is set

"S" in the group permissions = file is not executable and set-group-ID mode is set

"T" in the other permission = sticky bit is set, but not execute
                              or search permission.

Result: User can execute SUID, group cannot execute, others cannot search
or execute; sticky bit is set.
