Let G be an arbitrary simple graph of order n. G is called strongly asymmetric if all induced overgraphs of G of order (n + 1) are nonisomorphic. In this paper we give some properties of such graphs and prove that the class 6ec of all connected strongly asymmetric graphs is infinite. In this paper
## Abstract We prove that for every __k__ there is a __k__βchromatic graph with a __k__βcoloring where the neighbors of each colorβclass form an independent set. This answers a question raised by N. J. A. Harvey and U. S. R. Murty [4]. In fact we find the smallest graph __G__~__k__~ with the requir
