Abstract:A graph G with vertex set V is said to have a prime labeling if its vertices can be labeled with distinct integers 1, 2, . . . , vertical bar V vertical bar such that for every edge xy in E, the labels assigned to x and y are relatively prime or coprime. In this paper, we show that the Knodel graph W-3,W-n is prime for n <= 130.
