<｜begin▁of▁sentence｜>### Instruction:
Given a cycle graph on four nodes, if we contract nodes 1 and 3, what is the resulting graph and is it isomorphic to the path graph P3? Also, what are the edges of the resultant contracted graph?
### Response:
import networkx as nx

# Create a graph
G = nx.cycle_graph(4)

# Contract nodes 1 and 3
M = nx.contracted_nodes(G, 1, 3)

# Check if the resultant graph is isomorphic to path graph P3
is_isomorphic_to_P3 = nx.is_isomorphic(M, nx.path_graph(3))
print('Is isomorphic to P3:', is_isomorphic_to_P3)
print('Edges of contracted graph:', M.edges())
