For example, {5,6,7,8} = {4+1,4+2,4+3,4 = 4x2+0} is isomorphic to {1, 2,3,0}, then any four consecutive integers are a cycle and isomorphic to Z4.

I see. Now let's consider the calculation. The operation is +4. If e is an element, by definition, a+4=a? ∈{Z4，+4}。

Only 0 (that is, 4) is a dollar. In other words, integers of type 4n or (i.e.) 4n+4 are unary.

The reason is easy to understand. For example, 5=4+ 1 is isomorphic to 1, 5+ 16 = 5+4x4 = 4x5+ 1 is isomorphic to 1, because 16 is a multiple of 4. In other words, in

Is that clear enough?

It is very simple to start with the definition when considering the problem.
