<｜begin▁of▁sentence｜>### Instruction:
Given a distance-regular graph like an icosahedral graph, how can you compute its intersection array using NetworkX, and what does the resulting array represent?
### Response:
import networkx as nx

# Create a distance-regular graph, such as an icosahedral graph
G = nx.icosahedral_graph()

# Calculate the intersection array of the graph
b, c = nx.intersection_array(G)

print('Intersection array:')
print('b:', b)
print('c:', c)
