Description
The number of spanning subgraphs of a graph.
This is the number of subsets of the edge set of the graph, or the evaluation of the Tutte polynomial at $x=y=2$.
Code
def statistic(x):
    return 2^x.num_edges()

def statistic_alternative(g):
    return g.tutte_polynomial().subs(x=Integer(2),y=Integer(2))
