Abstract :
The concept of Lucky $k$-polynomials was recently introduced for null and complete split graphs. This paper extends on the introductory work and presents Lucky $\chi$-polynomials ($k=\chi(G)$) for graphs of order 5. The methodical work done for graphs of order 5 serves mainly to set out the fundamental method to be used for all other classes of graphs. Finally, further problems for research related to this concept are presented.
