A range set D in G°H is a girth 2-dominating set of G°H if every vertex in V-D is adjacent to atleast two vertex of girth graph is called the Irredundant girth 2-dominating set. the matching number is the maximum cardinality of a matching of G, while the irredundant girth 2-domination number of G°H is the minimum cardinality taken over all irredundant girth 2-domination number and is denoted by γm2irg;(G°H).
