The global cototal domination number __ampersandsigngamma;gcot(G) is the minimum cardinality of a global cototal domination set of G. In this paper we determine the value of the global cototal domination number __ampersandsigngamma;gcot(G) for Friendship graph, Helm graph, Trestled graph, Total graph, Web graph and Grid graph.
