Abstract
The chordal ring of order n, denoted by CRn(x, y, z), is the graph with vertex set Z(n), an additive group of integers modulo n, and adjacencies given by i similar to i + x, i similar to i + y, i similar to i + z for all even vertex i and distinct odd integers x, y, z in [1, n-1]. In this paper, we provide super vertex-magic total labeling of CRn (1, 3, 5), n equivalent to 0(mod 4) and (a, d)-antimagic labeling of CRn (1, 3, 7), n equivalent to 0(mod 4).
