<｜begin▁of▁sentence｜>### Instruction:
Given two graphs, G1 with edges [(0,1), (1,2), (2,0)] and G2 with edges [(3,4), (4,5), (5,3)], can you check if they could possibly be isomorphic without guaranteeing it?
### Response:
import networkx as nx

# Create two graphs
G1 = nx.Graph()
G1.add_edges_from([(0,1), (1,2), (2,0)])

G2 = nx.Graph()
G2.add_edges_from([(3,4), (4,5), (5,3)])

# Use the fast_could_be_isomorphic function to check if the graphs could be isomorphic
isomorphic_possibility = nx.fast_could_be_isomorphic(G1, G2)
print('The graphs could be isomorphic:', isomorphic_possibility)
