Abstract
We give a brief review on recent developments of Zn2-graded symmetry in physics in which hidden Zn2-graded symmetries and Zn2-graded extensions of known systems are discussed. This elucidates physical relevance of the Zn2-graded algebras. As an example of physically interesting algebra, we take Z22-graded supersymmetry (SUSY) algebras and consider their irreducible representations (irreps). A list of irreps for N=1,2 algebras is presented and as an application of the irreps, Z22-graded SUSY classical actions are constructed.

Strengths
1. The paper contains a very nice review of applications of Z22 and more generaly Zn2 graded algebra in physics. In particular the connection with symmetries of Levy-Leblond equation, mixed parabosons and parafermions and clifford algebras. The section 2.2 contain further context in which they have applications.
2. The subsection 3.1 present details of the irreducible representations. The results seems correct and are nicely summarized.
3. The subsection 3.2 is particularly relevant for this journal as it provide some insight into construction of Z_2^2 graded SUSY classical mechanics.
4. The paper is well written and has appropriate references.
Weaknesses
I don't see obvious weaknesses in this paper. The author has contributed to this area quite actively in recent years and the paper is a nice addition to this proceeding which summarises results in the area.
Report
I recommend the paper to be accepted for publication in this journal as it meet the criteria.
