If so, then provide the "name" of that subgraph (i.e., Cn) along with a formal representation. d. Does this graph contain a subgraph that is one of the "complete" graphs? If so, then provide the "name" of that subgraph (i.e, Kn) along with a formal representation e. Provide the formal representation of a spanning tree of the largest connected component of this graph
