## Comnnmicated by G. Berge In [3] Galeana-Stinchez and Neumann-Lara have deveioped a genera! method to extend kernel-perfect graphs to kernel-perfect critical graphs. In this note we construct a class of kernel-perfect critical graphs which can be used to extend any kernel-perfect graph. For gen

## Abstract The concept of the line graph can be generalized as follows. The __k__‐line graph __L__~__k__~(__G__) of a graph __G__ is defined as a graph whose vertices are the complete subgraphs on __k__ vertices in __G.__ Two distinct such complete subgraphs are adjacent in __L__~__k__~(__G__) if
