<｜begin▁of▁sentence｜>### Instruction:
Given a graph with edge set [(0, 1), (1, 2), (0, 2), (3, 4), (4, 5), (3, 5)], can you use the clique_number function to find the size of the largest clique in the graph?
### Response:
from igraph import Graph

# Create a graph with some edges
edges = [(0, 1), (1, 2), (0, 2), (3, 4), (4, 5), (3, 5)]
g = Graph(edges=edges, directed=False)

# Find the clique number (size of the largest clique)
clique_num = g.clique_number()

print('The clique number of the graph is:', clique_num)
