consider the following definition: A subgraph H of a graph $G$ is called an elementary subgraph if each component of $H$ is either an edge or a cycle of length at least $3$. A spanning elementary subgraph is a subgraph having all components either path or cycles. Now my problem is: Consider the following code:
G=graphs.EmptyGraph()
G.add_edges([(1,2),(2,3),(3,4),(4,5),(5,2),(6,5),(6,7)])
G.show()
Can we have a sage code that gives all possible spanning subgraphs on $6$ vertices of the above graph
