The set $pi_{e}(G)$ determines the prime graph (or Grunberg-Kegel graph) $Gamma(G)$ whose vertex set is $pi(G)$, the set of primes dividing the order of $G$, and two vertices $p$ and $q$ are adjacent if and only if $pqinpi_{e}(G)$. The degree $deg(p)$ of a vertex $pin pi(G)$, is the number of edges incident on $p$. Let $pi(G)={p_{1},p_{2},...,p_{k}}$ with $p_{1} }, URL = {http://ijmsi.ir/article-1-382-en.html}, eprint = {http://ijmsi.ir/article-1-382-en.pdf}, journal = {Iranian Journal of Mathematical Sciences and Informatics}, doi = {10.7508/ijmsi.2015.01.003}, year = {2015} }
