Understand the cluster.out in mcsqs method

I have viewed the previous post:

I still have some question about the cluster.out, like,

192
1.06066
2
0.50000 0.75000 0.75000 2 0
0.75000 1.00000 0.75000 2 0

How to define the "2 0" ? you say, it is a function type. What the specific theory of this kind function. I get some infortmation from the manual. For a binary system, it will be "0 0". For a ternary system, it will be "0 0", "1 0", "1 1".
Can you give me a example to explain it, like, for a ABC ternary alloy, what the "0 0", "1 0", "1 1" actually mean?

This is explained in
https://dx.doi.org/10.1016/j.calphad.2008.12.005
or
https://arxiv.org/abs/0906.1608

and in the manual you get with
