In phylogenetic networks, some of the branches of tree combine and create a reticulation node. Level of a network is decided to look at how many nodes in a connected component in a network. In this research, Int this paper, the structure of directed and undirected level-2 networks and how the can be decomposed into level-2 generators is studied..eninfo:eu-repo/semantics/openAccessArticle10.17776/csj.10713494411301421162892
