##### Abstract:

The notion of a perfect coloring, introduced by Delsarte, generalizes the concept of completely regular code. A perfect z-colorings of a graph is a partition of its vertex set. It splits vertices into z parts P1, , Pz such that for all i, j 2 f1, , zg, each vertex of Pi is adjacent to pij, vertices of Pj. The matrix P = (pij)i,j2f1, ,zg, is called parameter matrix. In this article, we classify all the realizable parameter matrices of perfect 4-colorings of some the generalized peterson graph.

##### Keywords:

Parameter matrices, Perfect coloring, Equitable partition, Generalized peterson graph.
