A graph G has a representation modulo r if there exists an injective map f : V (G) → {0, 1, . . . , r − 1} such that vertices u and v are adjacent if and only if f(u) − f(v) is relatively prime to r. The representation number rep(G) is the smallest positive integer r for which G has a representation modulo r. In this paper we study representation numbers of the stars K1,n. We will show that the...
