Set of integers,
Zn is split into even-odd parts. The even part is arranged in

ways, while the odd part fixes one point at a time to compliment the even part thereby forming the semigroup,
AZn. Thus,
![](//file.scirp.org/image/Edit_09d616ae-22c7-483c-951d-5e8b6ccb8b10.png)
-spaces are filled choosing maximum of two even points at a time. Green’s relations have formed important structures that enhance the algebraic study of transformation semigroups. The semigroup of Alternating Nonnegative Integers for
n-even (
AZn-even) is shown to have only two D-classes,

and there are

-classes for n
≥4. The cardinality of L-classes is constant. Certain cardinalities and some other properties were derived. The coefficients of the zigzag triples obtained are 1,

and

. The second and third coefficients can be obtained by zigzag addition.
