The graph of subgroups lattice is denoted by . A subset of is double dominating set of if for every vertex , , that is in and has at least one neighbour in or and has at least two neighbours in . The double domination number in subgroup lattice is a minimum cardinality of double dominating set. In this paper some upper and sharp bounds on are obtained </p>}, number={12s}, journal={International Journal of Advanced Science and Technology}, author={Suhas P.
