Are you talking about a computer package or a math structure?

I am talking about the mathematical (algebraic) structure GAMMA NEAR-RING

Γ- Near- Fields and bi-ideals, Commutativity in Prime Gamma Near-Rings with Permuting Tri-derivations, GENERALIZED PSEUDO COMMUTATIVE GAMMA NEAR-RINGS, PRIME GAMMA-NEAR-RINGS WITH (σ, τ)-DERIVATIONS, Fuzzy Ideals , and many more

In addition to what has been observed by @Abul Basar,  consider the work on gamma near fields in

E. Domi, Gamma-near-fields and the characterization by bi-ideals, Gen. Math. Notes 19 (1), 2013, 35-42:

A gamma near ring is called a gamma near field provided it has an identity element, at least one nonzero element and every nonzero element has a unique inverse element (see page 37).    Gamma near fields are characterized by bi-ideals (see Section 4, starting on page 40). 

The commutivity of prime gamma near rings is investigated in

A.M. Ibraheem, On the commutativity of prime gamma near rings, IOSR J of Math. 10 (2), 2014, 68-71:

http://www.iosrjournals.org/iosr-jm/full-issue/JM-10(2)v6.pdf

which references earlier work on semiprime gamma near rings (Y.U. Cho and Y.B. Jun, 2002), prime near rings (Y.U. Cho, 2001 and M. Uckun, M.A. Ozturk, Y.B. Jun, 2004).

In my previous post, the link to

A.M. Ibraheem, On the commutativity of prime gamma near rings, IOSR J of Math. 10 (2), 2014, 68-71

should be

http://iosrjournals.org/iosr-jm/papers/Vol10-issue2/Version-6/K010266871.pdf

This is version VI of the paper.   I am assuming that this means that this paper went through VI revisions before it was accepted.   Perhaps Afrah Mohammed Ibraheem can comment on this. 

The numbering of the references for this paper has mistakes.    References

[2] and [3] are the same paper, and

[8] and [9] are the same paper.

The paper

M. Uckun, M.A.Ozturk and Y.B.Jun, On prime gamma-near-rings with derivations, Commun. Korean Math. Soc. 19(3), 2004, 427-433

is a very good paper that includes a thorough overview of previous work on gamma-near rings.
