what does it mean (6.4.0)?

[Kime11]

For instance Greek Monarhy (6.4.0)... or (5.5.0) in right lower corner when playing game??

I know the first two numbers are the percentage of your revenue that is going to science and luxury. So in the first example you have your taxes going to 60% science research and 40% luxuries. I don't know what the last number is. I know this question has been brought up many times and every time I forget what the numbers mean again, so you are not alone in your confusion!

EDIT: I think viper275 is correct.

First is tax, second science, third luxuries. So 6.4.0 is 60% tax, 40% research, and 0% luxuries.
