I think we usually use the 0x notation for hex values?

0x00?

I assume that this means that 0-4 are reserved for these error codes and
may not be used for something else, while 'other' is basically where
each group type may define their specific error codes? So maybe make the
last line

0x05 - & - & group type specific group administration command error \\
