Abstract

For example  is a chromatic number with the smallest integer so that the graph  has a true vertex coloring with k color. Chromatic number is still an interesting study which is still being studied for its development through graph coloring. Graph coloring is a special case of graph labeling. Labeling here means, giving color to the points at a certain limit so that no two vertices have the same color. This study aims to calculate the chromatic number in several classes of graphs including , ,  Based on the results of the study, generalization of the chromatic number of the graph class . Class  and for class  for even n and 4 for odd n.
