That's the Unix file access permissions of the original file, in octal.
The three digits represent permissions for the file owner, the owner's
group, and all other users. The the bits of each digit represent read,
write, and execute permissions. The most common set of permissions for
an ordinary file is read and write but not execute for everyone, thus
666. Executables will be 777 or 555. Other common values are to give
permission to owner and group but not everyone, which is 664.
